Potholes and Big Data: Crowdsourcing Our Way to Better Government


Phil Simon in Wired: “Big Data is transforming many industries and functions within organizations with relatively limited budgets.
Consider Thomas M. Menino, up until recently Boston’s longest-serving mayor. At some point in the past few years, Menino realized that it was no longer 1950. Perhaps he was hobnobbing with some techies from MIT at dinner one night. Whatever his motivation, he decided that there just had to be a better, more cost-effective way to maintain and fix the city’s roads. Maybe smartphones could help the city take a more proactive approach to road maintenance.
To that end, in July 2012, the Mayor’s Office of New Urban Mechanics launched a new project called Street Bump, an app that allows drivers to automatically report the road hazards to the city as soon as they hear that unfortunate “thud,” with their smartphones doing all the work.
The app’s developers say their work has already sparked interest from other cities in the U.S., Europe, Africa and elsewhere that are imagining other ways to harness the technology.
Before they even start their trip, drivers using Street Bump fire up the app, then set their smartphones either on the dashboard or in a cup holder. The app takes care of the rest, using the phone’s accelerometer — a motion detector — to sense when a bump is hit. GPS records the location, and the phone transmits it to an AWS remote server.
But that’s not the end of the story. It turned out that the first version of the app reported far too many false positives (i.e., phantom potholes). This finding no doubt gave ammunition to the many naysayers who believe that technology will never be able to do what people can and that things are just fine as they are, thank you. Street Bump 1.0 “collected lots of data but couldn’t differentiate between potholes and other bumps.” After all, your smartphone or cell phone isn’t inert; it moves in the car naturally because the car is moving. And what about the scores of people whose phones “move” because they check their messages at a stoplight?
To their credit, Menino and his motley crew weren’t entirely discouraged by this initial setback. In their gut, they knew that they were on to something. The idea and potential of the Street Bump app were worth pursuing and refining, even if the first version was a bit lacking. Plus, they have plenty of examples from which to learn. It’s not like the iPad, iPod, and iPhone haven’t evolved considerably over time.
Enter InnoCentive, a Massachusetts-based firm specializing in open innovation and crowdsourcing. The City of Boston contracted InnoCentive to improve Street Bump and reduce the amount of tail chasing. The company accepted the challenge and essentially turned it into a contest, a process sometimes called gamification. InnoCentive offered a network of 400,000 experts a share of $25,000 in prize money donated by Liberty Mutual.
Almost immediately, the ideas to improve Street Bump poured in from unexpected places. This crowd had wisdom. Ultimately, the best suggestions came from:

  • A group of hackers in Somerville, Massachusetts, that promotes community education and research
  • The head of the mathematics department at Grand Valley State University in Allendale, MI.
  • An anonymous software engineer

…Crowdsourcing roadside maintenance isn’t just cool. Increasingly, projects like Street Bump are resulting in substantial savings — and better government.”

Randomized control trials (RCTs): interesting, but a marginal tool for governments


ODI Researcher Philipp Krause at BeyondBudgets: “Randomized control trials (RCTs) have had a great decade. The stunning line-up of speakers who celebrated J-PAL’s tenth anniversary in Boston last December gives some indication of just how great. They are the shiny new tool of development policy, and a lot of them are pretty cool. Browsing through J-PAL’s library of projects, it’s easy to see how so many of them end up in top-notch academic journals.
So far, so good. But the ambition of RCTs is not just to provide a gold-standard measurement of impact. They aim to actually have an impact on the real world themselves. The scenario goes something like this: researchers investigate the effect of an intervention and use the findings to either get out of that mess quickly (if the intervention doesn’t work) or scale it up quickly (if it does). In the pursuit of this impact-seeker’s Nirvana, it’s easy to conflate a couple of things, notably that an RCT is not the only way to evaluate impact; and evaluating impact is not the only way to use evidence for policy. Unfortunately, it is now surprisingly common to hear RCTs conflated with evidence-use, and evidence-use equated with the key ingredient for better public services in developing countries. The reality of evidence use is different.
Today’s rich countries didn’t get rich by using evidence systematically. This is a point that we recently discussed at a big World Bank – ODI conference on the (coincidental?) tenth anniversary of the WDR 2004. Lant Pritchett made it best when describing Randomistas as engaging in faith-based activity: nobody could accuse the likes of Germany, Switzerland, Sweden or the US of achieving human development by systematically scaling up what works.
What these countries do have in spades is people noisily demanding stuff, and governments giving it to them. In fact, some of the greatest innovations in providing health, unemployment benefits and pensions to poor people (and taking them to scale) happened because citizens seemed to want them, and giving them stuff seemed like a good way to shut them up. Ask Otto Bismarck. It’s not too much of a stretch to call this the history of public spending in a nutshell….
The bottom line is governments s that care about impact have plenty of cheaper, timelier and more appropriate tools and options available to them than RCTs. That doesn’t mean RCTs shouldn’t be done, of course. And the evaluation of aid is a different matter altogether, where donors are free to be as inefficient about evidence-basing as they wish without burdening poor countries.
But for governments the choice of how to go about using systematic evidence is theirs to make. And it’s a tough capability to pick up. Many governments choose not to do it, and there’s no evidence that they suffer for it. It would be wrong for donors to suggest to low-income countries that RCTs are in any way critical for their public service capability. Better call them what they are: interesting, but marginal.”

European Commission launches network to foster web talent through Massive Open Online Courses (MOOCs)


Press Release: “The Commission is launching a network of providers of MOOCs related to web and apps skills. MOOCs are online university courses which enable people to access quality education without having to leave their homes. The new network aims to map the demand for web-related skills across Europe and to promote the use of Massive Open Online Courses (MOOCs) for capacity-building in those fields.
Web-related industry is generating more economic growth than any other part of the European economy, but hundreds of thousands of jobs remain unfilled due to the lack of qualified staff.
European Commission Vice President Neelie Kroes, responsible for the Digital Agenda, said:
“By 2020, 90% of jobs will need digital skills. That is just around the corner, and we aren’t ready! Already businesses in Europe are facing a shortage of skilled ICT workers. We have to fill that gap, and this network we are launching will help us identify where the gaps are. This goes hand in hand with the work being done through the Grand Coalition for Digital Jobs”.
The Commission calls upon web entrepreneurs, universities, MOOC providers and online learners to join the network, which is part of the “Startup Europe” initiative.
Participants in the network benefit from the exchange of experiences and best practices, opportunities for networking, news updates, and the chance to participate in a conference dedicated to MOOCs for web and apps skills scheduled for the second half of 2014. In addition, the network offers a discussion group that can be found on the European Commission’s portal Open Education Europa. The initiative is coordinated by p.a.u. education and in partnership with Iversity.

Artists Show How Anyone Can Fight the Man with Open Data


MotherBoard: “The UK’s Open Data Institute usually looks, as you’d probably expect, like an office full of people staring at screens. But visit at the moment and you might see a potato gun among the desks or a bunch of drone photos on the wall—all in the name of encouraging public discussion around and engagement with open data.
The ODI was set up by World Wide Web inventor Tim Berners-Lee and interdisciplinary researcher Nigel Shadbolt in London to push for an open data culture, and from Monday it will be hosting the second Data as Culture exhibition, which presents a more artistic take on questions surrounding the practicalities of open data. In doing so, it shows quite how the general public can (and probably really should) use data to inform their own lives and to engage with political issues.
All of the exhibits are based on freely available data, which is made lot more animated and accessible than numbers in a spreadsheet. “I made the decision straight away to move away from anything screen-based,” curator Shiri Shalmy told me as she gave me a tour, winding through office workers tapping away on keyboards. “Everything had to be physical.”…
James Bridle’s work on drone warfare touches a similar theme, though in this case the data are not hidden: his images of military UAVs come from Google Maps. “They’re there for anybody to look at, they’re kind of secret but available,” said Shalmy, who added that with the data out there, we can’t pretend we don’t know what’s going on. “They can do things in secret as long as we pretend it’s a secret.”
We’ve looked at Bridle’s work before, from his Dronestagram photos to his chalk outlines of drones, and he’s been commissioned to do something new for the Data as Culture show: Shalmy has asked him to compare the open data on military drones against that of London’s financial centre. He’ll present what he digs up in summer.

Using this kind of government data—from local council expenses to military movements—shows quite how much information is available and how it can be used to hold politicians to account. In essence, anyone can do surveillance to some level. While activists including Berners-Lee push for more data to be made accessible, it’s only useful if we actually bother to engage with it, and work like Bridle’s pose the uneasy suggestion that sometimes it’s more comfortable to remain ignorant.
And in addition to reading data, we can collect it. Rather than delving into government files, a knitted banner by artist Sam Meech uses publicly generated data to make a political point. The banner bears the phrase “8 hour labour,” a reference to the eight-hour workday movement that sprang up in Britain’s Industrial Revolution. The idea was that people would have eight hours work, eight hours rest, and eight hours recreation.

A detail from Sam Meechan’s Punchcard Economy. Image: Sam Meechan/ODI

But the black-and-white pattern in the banner is made up of much less regular working hours: those logged by self-employed creatives, who can take part by entering their own timesheet data via virtual punchcards. Shalmy pointed out her own schedule in a week when she was setting up the exhibition: a 70-hour block woven into the knit. It’s an example of how individuals can use data to make a political point—the work is reminiscent of trade union banners and seems particularly relevant at a time when controversial zero hours contracts are on the rise.
Also garnering data from the public, artist collective Thickear are asking people to fill in data forms on their arrival, which they’ll file on an old-fashioned spike. I took one of the forms, only to be confronted with nonsensical bureaucratic-type boxes. “The data itself is not informative in any way,” said Shalmy. It’s more about the idea of who we trust to give our data to. How often do we accept privacy policies without even giving ourselves the chance to even blink at the small print?…”

Sinkhole of bureaucracy


First article in a Washington Post series “examining the failures at the heart of troubled federal systems” by David A. Fahrenthold: “The trucks full of paperwork come every day, turning off a country road north of Pittsburgh and descending through a gateway into the earth. Underground, they stop at a metal door decorated with an American flag.

Behind the door, a room opens up as big as a supermarket, full of five-drawer file cabinets and people in business casual. About 230 feet below the surface, there is easy-listening music playing at somebody’s desk.
This is one of the weirdest workplaces in the U.S. government — both for where it is and for what it does.
Here, inside the caverns of an old Pennsylvania limestone mine, there are 600 employees of the Office of Personnel Management. Their task is nothing top-secret. It is to process the retirement papers of the government’s own workers.
But that system has a spectacular flaw. It still must be done entirely by hand, and almost entirely on paper.

The employees here pass thousands of case files from cavern to cavern and then key in retirees’ personal data, one line at a time. They work underground not for secrecy but for space. The old mine’s tunnels have room for more than 28,000 file cabinets of paper records.
This odd place is an example of how hard it is to get a time-wasting bug out of a big bureaucratic system.
Held up by all that paper, work in the mine runs as slowly now as it did in 1977….”

Charities Try New Ways to Test Ideas Quickly and Polish Them Later


Ben Gose in the Chronicle of Philanthropy: “A year ago, a division of TechSoup Global began working on an app to allow donors to buy a hotel room for victims of domestic violence when no other shelter is available. Now that app is a finalist in a competition run by a foundation that combats human trafficking—and a win could mean a grant worth several hundred thousand dollars. The app’s evolution—adding a focus on sex slaves to the initial emphasis on domestic violence—was hardly accidental.
Caravan Studios, the TechSoup division that created the app, has embraced a new management approach popular in Silicon Valley known as “lean start-up.”
The principles, which are increasingly popular among nonprofits, emphasize experimentation over long-term planning and urge groups to get products and services out to clients as early as possible so the organizations can learn from feedback and make changes.
When the app, known as SafeNight, was still early in the design phase, Caravan posted details about the project on its website, including applications for grants that Caravan had not yet received. In lean-start-up lingo, Caravan put out a “minimal viable product” and hoped for feedback that would lead to a better app.
Caravan soon heard from antitrafficking organizations, which were interested in the same kind of service. Caravan eventually teamed up with the Polaris Project and the State of New Jersey, which were working on a similar app, to jointly create an app for the final round of the antitrafficking contest. Humanity United, the foundation sponsoring the contest, plans to award $1.8-million to as many as three winners later this month.
Marnie Webb, CEO of Caravan, which is building an array of apps designed to curb social problems, says lean-start-up principles help Caravan work faster and meet real needs.
“The central idea is that any product that we develop will get better if it lives as much of its life as possible outside of our office,” Ms. Webb says. “If we had kept SafeNight inside and polished it and polished it, it would have been super hard to bring on a partner because we would have invested too much.”….
Nonprofits developing new tech tools are among the biggest users of lean-start-up ideas.
Upwell, an ocean-conservation organization founded in 2011, scans the web for lively ocean-related discussions and then pushes to turn them into full-fledged movements through social-media campaigns.
Lean principles urge groups to steer clear of “vanity metrics,” such as site visits, that may sound impressive but don’t reveal much. Upwell tracks only one number—“social mentions”—the much smaller group of people who actually say something about an issue online.
After identifying a hot topic, Upwell tries to assemble a social-media strategy within 24 hours—what it calls a “minimum viable campaign.”
“We do the least amount of work to get something out the door that will get results and information,” says Rachel Dearborn, Upwell’s campaign director.
Campaigns that don’t catch on are quickly scrapped. But campaigns that do catch on get more time, energy, and money from Upwell.
After Hurricane Sandy, in 2012, a prominent writer on ocean issues and others began pushing the idea that revitalizing the oyster beds near New York City could help protect the shore from future storm surges. Upwell’s “I (Oyster) New York” campaign featured a catchy logo and led to an even bigger spike in attention.

‘Build-Measure-Learn’

Some organizations that could hardly be called start-ups are also using lean principles. GuideStar, the 20-year-old aggregator of financial information about charities, is using the lean approach to develop tools more quickly that meet the needs of its users.
The lean process promotes short “build-measure-learn” cycles, in which a group frequently updates a product or service based on what it hears from its customers.
GuideStar and the Nonprofit Finance Fund have developed a tool called Financial Scan that allows charities to see how they compare with similar groups on various financial measures, such as their mix of earned revenue and grant funds.
When it analyzed who was using the tool, GuideStar found heavy interest from both foundations and accounting firms, says Evan Paul, GuideStar’s senior director of products and marketing.
In the future, he says, GuideStar may create three versions of Financial Scan to meet the distinct interests of charities, foundations, and accountants.
“We want to get more specific about how people are using our data to make decisions so that we can help make those decisions better and faster,” Mr. Paul says….


Lean Start-Up: a Glossary of Terms for a Hot New Management Approach

Build-Measure-Learn

Instead of spending considerable time developing a product or service for a big rollout, organizations should consider using a continuous feedback loop: “build” a program or service, even if it is not fully fleshed out; “measure” how clients are affected; and “learn” by improving the program or going in a new direction. Repeat the cycle.

Minimum Viable Product

An early version of a product or service that may be lacking some features. This approach allows an organization to obtain feedback from clients and quickly determine the usefulness of a product or service and how to improve it.

Get Out of the Building

To determine whether a product or service is needed, talk to clients and share your ideas with them before investing heavily.

A/B Testing

Create two versions of a product or service, show them to different groups, and see which performs best.

Failing Fast

By quickly realizing that a product or service isn’t viable, organizations save time and money and gain valuable information for their next effort.

Pivot

Making a significant change in strategy when the early testing of a minimum viable product shows that the product or service isn’t working or isn’t needed.

Vanity Metrics

Measures that seem to provide a favorable picture but don’t accurately capture the impact of a product. An example might be a tally of website page views. A more meaningful measure—or an “actionable metric,” in the lean lexicon—might be the number of active users of an online service.

Statistics and Open Data: Harvesting unused knowledge, empowering citizens and improving public services


House of Commons Public Administration Committee (Tenth Report):
“1. Open data is playing an increasingly important role in Government and society. It is data that is accessible to all, free of restrictions on use or redistribution and also digital and machine-readable so that it can be combined with other data, and thereby made more useful. This report looks at how the vast amounts of data generated by central and local Government can be used in open ways to improve accountability, make Government work better and strengthen the economy.

2. In this inquiry, we examined progress against a series of major government policy announcements on open data in recent years, and considered the prospects for further development. We heard of government open data initiatives going back some years, including the decision in 2009 to release some Ordnance Survey (OS) data as open data, and the Public Sector Mapping Agreement (PSMA) which makes OS data available for free to the public sector.  The 2012 Open Data White Paper ‘Unleashing the Potential’ says that transparency through open data is “at the heart” of the Government’s agenda and that opening up would “foster innovation and reform public services”. In 2013 the report of the independently-chaired review by Stephan Shakespeare, Chief Executive of the market research and polling company YouGov, of the use, re-use, funding and regulation of Public Sector Information urged Government to move fast to make use of data. He criticised traditional public service attitudes to data before setting out his vision:

    • To paraphrase the great retailer Sir Terry Leahy, to run an enterprise without data is like driving by night with no headlights. And yet that is what Government often does. It has a strong institutional tendency to proceed by hunch, or prejudice, or by the easy option. So the new world of data is good for government, good for business, and above all good for citizens. Imagine if we could combine all the data we produce on education and health, tax and spending, work and productivity, and use that to enhance the myriad decisions which define our future; well, we can, right now. And Britain can be first to make it happen for real.

3. This was followed by publication in October 2013 of a National Action Plan which sets out the Government’s view of the economic potential of open data as well as its aspirations for greater transparency.

4. This inquiry is part of our wider programme of work on statistics and their use in Government. A full description of the studies is set out under the heading “Statistics” in the inquiries section of our website, which can be found at www.parliament.uk/pasc. For this inquiry we received 30 pieces of written evidence and took oral evidence from 12 witnesses. We are grateful to all those who have provided evidence and to our Specialist Adviser on statistics, Simon Briscoe, for his assistance with this inquiry.”

Building a More Open Government


Corinna Zarek at the White House: “It’s Sunshine Week again—a chance to celebrate transparency and participation in government and freedom of information. Every year in mid-March, we take stock of our progress and where we are headed to make our government more open for the benefit of citizens.
In December, 2013, the Administration announced 23 ambitious commitments to further open up government over the next two years in U.S. Government’s  second Open Government National Action Plan. Those commitments are now all underway or in development, including:
·         Launching an improved Data.gov: The updated Data.gov debuted in January, 2014, and continues to grow with thousands of updated or new government data sets being proactively made available to the public.
·         Increasing public collaboration: Through crowdsourcing, citizen science, and other methods, Federal agencies continue to expand the ways they collaborate with the public. For example, the National Aeronautics and Space Administration, for instance, recently launched its third Asteroid Grand Challenge, a broad call to action, seeking the best and brightest ideas from non-traditional partners to enhance and accelerate the work NASA is already doing for planetary defense.
·         Improving We the People: The online petition platform We the People gives the public a direct way to participate in their government and is currently incorporating improvements to make it easier for the public to submit petitions and signatures.”

New Field Guide Explores Open Data Innovations in Disaster Risk and Resilience


Worldbank: “From Indonesia to Bangladesh to Nepal, community members armed with smartphones and GPS systems are contributing to some of the most extensive and versatile maps ever created, helping inform policy and better prepare their communities for disaster risk.
In Jakarta, more than 500 community members have been trained to collect data on thousands of hospitals, schools, private buildings, and critical infrastructure. In Sri Lanka, government and academic volunteers mapped over 30,000 buildings and 450 km of roadways using a collaborative online resource called OpenStreetMaps.
These are just a few of the projects that have been catalyzed by the Open Data for Resilience Initiative (OpenDRI), developed by the World Bank’s Global Facility for Disaster Reduction and Recovery (GFDRR). Launched in 2011, OpenDRI is active in more than 20 countries today, mapping tens of thousands of buildings and urban infrastructure, providing more than 1,000 geospatial datasets to the public, and developing innovative application tools.
To expand this work, the World Bank Group has launched the OpenDRI Field Guide as a showcase of successful projects and a practical guide for governments and other organizations to shape their own open data programs….
The field guide walks readers through the steps to build open data programs based on the OpenDRI methodology. One of the first steps is data collation. Relevant datasets are often locked because of proprietary arrangements or fragmented in government bureaucracies. The field guide explores tools and methods to enable the participatory mapping projects that can fill in gaps and keep existing data relevant as cities rapidly expand.

GeoNode: Mapping Disaster Damage for Faster Recovery
One example is GeoNode, a locally controlled and open source cataloguing tool that helps manage and visualize geospatial data. The tool, already in use in two dozen countries, can be modified and easily be integrated into existing platforms, giving communities greater control over mapping information.
GeoNode was used extensively after Typhoon Yolanda (Haiyan) swept the Philippines with 300 km/hour winds and a storm surge of over six meters last fall. The storm displaced nearly 11 million people and killed more than 6,000.
An event-specific GeoNode project was created immediately and ultimately collected more than 72 layers of geospatial data, from damage assessments to situation reports. The data and quick analysis capability contributed to recovery efforts and is still operating in response mode at Yolandadata.org.
InaSAFE: Targeting Risk Reduction
A sister project, InaSAFE, is an open, easy-to-use tool for creating impact assessments for targeted risk reduction. The assessments are based on how an impact layer – such as a tsunami, flood, or earthquake – affects exposure data, such as population or buildings.
With InaSAFE, users can generate maps and statistical information that can be easily disseminated and even fed back into projects like GeoNode for simple, open source sharing.
The initiative, developed in collaboration with AusAID and the Government of Indonesia, was put to the test in the 2012 flood season in Jakarta, and its successes provoked a rapid national rollout and widespread interest from the international community.
Open Cities: Improving Urban Planning & Resilience
The Open Cities project, another program operating under the OpenDRI platform, aims to catalyze the creation, management and use of open data to produce innovative solutions for urban planning and resilience challenges across South Asia.
In 2013, Kathmandu was chosen as a pilot city, in part because the population faces the highest mortality threat from earthquakes in the world. Under the project, teams from the World Bank assembled partners and community mobilizers to help execute the largest regional community mapping project to date. The project surveyed more than 2,200 schools and 350 health facilities, along with road networks, points of interest, and digitized building footprints – representing nearly 340,000 individual data nodes.”

After the Protests


Zeynep Tufekc in the New York Times on why social media is fueling a boom-and-bust cycle of political: “LAST Wednesday, more than 100,000 people showed up in Istanbul for a funeral that turned into a mass demonstration. No formal organization made the call. The news had come from Twitter: Berkin Elvan, 15, had died. He had been hit in the head by a tear-gas canister on his way to buy bread during the Gezi protests last June. During the 269 days he spent in a coma, Berkin’s face had become a symbol of civic resistance shared on social media from Facebook to Instagram, and the response, when his family tweeted “we lost our son” and then a funeral date, was spontaneous.

Protests like this one, fueled by social media and erupting into spectacular mass events, look like powerful statements of opposition against a regime. And whether these take place in Turkey, Egypt or Ukraine, pundits often speculate that the days of a ruling party or government, or at least its unpopular policies, must be numbered. Yet often these huge mobilizations of citizens inexplicably wither away without the impact on policy you might expect from their scale.

This muted effect is not because social media isn’t good at what it does, but, in a way, because it’s very good at what it does. Digital tools make it much easier to build up movements quickly, and they greatly lower coordination costs. This seems like a good thing at first, but it often results in an unanticipated weakness: Before the Internet, the tedious work of organizing that was required to circumvent censorship or to organize a protest also helped build infrastructure for decision making and strategies for sustaining momentum. Now movements can rush past that step, often to their own detriment….

But after all that, in the approaching local elections, the ruling party is expected to retain its dominance.

Compare this with what it took to produce and distribute pamphlets announcing the Montgomery bus boycott in 1955. Jo Ann Robinson, a professor at Alabama State College, and a few students sneaked into the duplicating room and worked all night to secretly mimeograph 52,000 leaflets to be distributed by hand with the help of 68 African-American political, religious, educational and labor organizations throughout the city. Even mundane tasks like coordinating car pools (in an era before there were spreadsheets) required endless hours of collaborative work.

By the time the United States government was faced with the March on Washington in 1963, the protest amounted to not just 300,000 demonstrators but the committed partnerships and logistics required to get them all there — and to sustain a movement for years against brutally enforced Jim Crow laws. That movement had the capacity to leverage boycotts, strikes and demonstrations to push its cause forward. Recent marches on Washington of similar sizes, including the 50th anniversary march last year, also signaled discontent and a desire for change, but just didn’t pose the same threat to the powers that be.

Social media can provide a huge advantage in assembling the strength in numbers that movements depend on. Those “likes” on Facebook, derided as slacktivism or clicktivism, can have long-term consequences by defining which sentiments are “normal” or “obvious” — perhaps among the most important levers of change. That’s one reason the same-sex marriage movement, which uses online and offline visibility as a key strategy, has been so successful, and it’s also why authoritarian governments try to ban social media.

During the Gezi protests, Prime Minister Recep Tayyip Erdogan called Twitter and other social media a “menace to society.” More recently, Turkey’s Parliament passed a law greatly increasing the government’s ability to censor online content and expand surveillance, and Mr. Erdogan said he would consider blocking access to Facebook and YouTube. It’s also telling that one of the first moves by President Vladimir V. Putin of Russia before annexing Crimea was to shut down the websites of dissidents in Russia.
Media in the hands of citizens can rattle regimes. It makes it much harder for rulers to maintain legitimacy by controlling the public sphere. But activists, who have made such effective use of technology to rally supporters, still need to figure out how to convert that energy into greater impact. The point isn’t just to challenge power; it’s to change it.”
