The first Liberation Technology seminar of the winter quarter on January 6, featured Jonathan Zittrain, Professor of Law at Harvard Law School and co-founder of the Berkman Center for Internet & Society at Harvard University. Zittrain focused his talk entitled, Minds for Sale, on the variety of online platforms that harness the wisdom of crowds today, and closed with a discussion of the implications of these platforms. Categorizing these new tools by the breadth of their user base, Zittrain began by describing the platforms that pay the most money per task, require the most skill, and subsequently have the least participation. Key examples of these platforms are listed below, and organized by their decreasing level on skill.

•  Xprize Foundation attempts to prompt radical breakthroughs through competitions for large quantities of prize money.
• InnoCentive creates a marketplace between engineers and scientists to encourage innovation.
• LiveOps, which bills itself as a contact center cloud, has developed a large set of independent contractors who are designated specific tasks when they sign in to the site. They may be assigned to answer calls placed to a restaurant or emergency hotline or to make political calls on behalf of Liveops clients.
• Samasource offers "dignified digital work for women, children and refugees" located in developing countries.
• Amazon Mechanical Turk (also known as Artificial Artificial Intelligence) allows users to participate in anonymous, minimally paid tasks. These tasks can be submitted by any party and are highly disaggregated among hundreds or thousands of users, each of whom receives a payout of between approximately one to fifteen cents for completing the task.
• Soylent, which calls itself "a word processor with a crowd inside" embeds workers from Mechanical Turk into Microsoft Word. When users install the site's Shortn add-in into Microsoft Word, they can use the tool to have written samples shortened in two minutes. In order to achieve this, the written sample is disaggregated by paragraphs, and each paragraph is shortened within two minutes by a "Turker"-a user who accepts the task on Mechanical Turk.
• Microtask enables disaggregating previously sensitive data to be work processed from a scanned image. The ultimate goal of this group is to put distributed work into video and computer games. For now, they disaggregate larger tasks into two-second tasks that can be distributed across a crowd.
• Games With A Purpose (GWAP) has a game-like platform designed to get users to complete disaggregated tasks for virtual points, rather than for actual remuneration. One of its more popular activities quickly attracted 23,000 players who contributed 4.1 million labels to images they were presented with in The ESP Game. Many players routinely play more than 20 hours a week.

Next, Zittrain moved on to offer some additional examples, hypothetical scenarios and questions that highlight some of his own concerns about the potential of these technologies. One key question is whether this market may be too efficient at linking up solvers and payers, if certain tasks are not in fact beneficial for society. After all, it was highly contentious when Texas governor Rick Perry set up video cameras on Texas' border with Mexico and invited people to watch the video feeds and report if they saw anything suspicious. Similarly, a site called InternetEyes allows users to watch video feed from CCTV cameras in the UK for free, offering the chance to "earn reward money, have a chance at reducing crime, and potentially become a hero and save lives," instead of actual compensation.

In another example, the University of Colorado Police Department recently offered a $50 reward for identification of students shown to be smoking marijuana in photos from a large April 20 gathering. Hypothetically, the Iranian government could use Turkers to identify Iranian protestors through national ID photographs in the very same way; by Zittrain's calculations, this task could be disaggregated and carried out quickly at a cost of only $17,000 per protester identified.

Another cluster of issues relates to the use of anonymous users to carry out disaggregated tasks that may have the effect of exerting influence on others. For example, Turkers were recently offered the opportunity to write a positive 5 out of 5 review for a product on a website, which hundreds accepted and completed for a few cents at a time. Users on SubvertandProfit.com are paid to "Like" something on Facebook, "Digg" something, or show their approval of a site or product via some other social network. The users are remunerated for their effort, and the site also profits. Taking this a step further, these platforms also enable users to pay people to evince opinions on legislative issues they do not actually care about. For example, health insurers were recently caught paying Facebook gamers virtual currency to oppose the health reform bill. By enabling any task to be disaggregated and monetized, these new platforms can have highly controversial and unethical implications.

Nathan Eagle, Founder and CEO of txteagle spoke at the weekly Liberation Technology Seminar Series on Dececember 2, 2010 about mobile phone usage in the developing world.

Although txteagle began in 2007 as a purely academic project, the current goal of the company and of its founder and CEO, Nathan Eagle, is to give one billion people a five percent raise. In his presentation, Eagle described the context for which txteagle was designed, how the company's focus has evolved over the past three years, and what steps the company is taking to move closer to achieving this goal in the future.

Eagle began by offering some background information to explain the initial impetus behind txteagle. Today, about 63% of global mobile phone usage takes place in the developing world, making airtime usage in emerging markets worth about $200 billion a year. Mobile phone users at the so-called "Base of the Pyramid" typically spend 10% of their income on mobile phone airtime. Through his experience living in emerging markets and teaching mobile application development in universities across sub-Saharan Africa, Eagle began to see that a significant opportunity space existed to reduce the cost of airtime for people at the base of the pyramid, in effect giving these people a raise.

Mobile applications developed as a part of MIT's Entrepreneurial Research on Programming and Research on Mobiles (EPROM) project offered some insights into the potential of mobile-based tools. In Rwanda, where electricity is a prepaid service, one of Eagle's former students quickly cornered a significant share of the market by creating scratch cards for crediting one's electricity bill via mobile phone. In Eastern Kenya, a program called SMS Blood Bank was created to enable real time monitoring of blood supplies at local district hospitals in Eastern Kenya. Although SMS reporting of low blood levels resolved the huge amount of latency in the system of local district hospitals (where responses to dips in supply had typically taken up to 4 weeks), the price of reporting blood levels via SMS represented a pay cut for local nurses; despite nurses' initial enthusiasm, SMS reporting tapered off within weeks. When the idea of sending about 10 cents of airtime to compensate nurses for each SMS report of blood level data proved a success, the model behind txteagle was born.

Designed as a means to monetize people's downtime, txteagle has grown rapidly through partnerships with over 220 mobile operators in about 80 countries around the world. In turn for helping these operators analyze their customer data, txteagle has gained access to about 2.1 billion mobile subscribers. Partnering with txteagle is a winning proposition for mobile operators, since the airtime compensation mobile subscribers receive from txteagle improves operators' Average Revenue per User (ARPU), a statistic that had been plummeting as more and more poor people became mobile phone users. By enabling people to carry out work via web browsers or SMS and compensating them via mobile money or airtime, txteagle has become a market leader at efficiently gathering data in the developing world.

Since txteagle was first created, the company has attempted to move from an outsourcing/back-office model to an emphasis on work that leverages a person's unique local knowledge and information. Typically outsourced tasks such as forms processing, audio transcription, inventory management, data cleaning, tagging, and internet search, tend to be less rewarding to the worker. By focusing on local data instead, txteagle enables unprecedented insight into emerging markets, all while optimizing engagement with local customers. Typical tasks include: maps and directions, local market prices and businesses, survey research and polling, and other forms of local knowledge gathering.

One of txteagle's central initiatives, GroundTruth, leverages this local knowledge-based model to carry out better market research. Today, global brands are already spending about $125 billion annually in emerging markets to engage the "next billion," but they typically carry out this research in a sub-optimal way. Through the txteagle platform, Eagle suggests, brands and organizations can use advertising money to design better products and services, conduct market research, and carry out brand engagement. Recent success cases include the use of txteagle to help a program of the United Nations to reach survey respondents directly and to enable the World Bank to obtain better local market price data at lower cost. 

Although txteagle's rapid growth and early successes have been encouraging, the company has ambitious goals for the next two years. The company began by focusing on outside sales through its GroundTruth market research program. Next year, the company  hopes to generate syndicated data and ultimately to create a self-source platform enabling anyone to conduct their own population-level surveys.  By continuing to focus on improving the quality of both their data and workers over time, txteagle aims to have an even greater positive impact on the incomes of the hundreds of millions of mobile phone users at the base of the pyramid.
