This vetting process occupies most of Carvin’s workdays. At first glance it looks much like the daily routine of many journalists, but it’s how Carvin became the talk of journalistic digerati a year ago, when he channeled his social-media savvy as a one-man newsroom covering the Arab Spring’s rolling upheaval.

Programming the Global Brain | May 2012 | Communications of the ACM
We still only poorly understand, however, how to "program" this global brain. We have some stunning success stories (such as Wikipedia, Google), but most applications still fail, or require a long series of trial-and-error refinements, for reasons we only poorly understand. Because people are involved, programming the global brain is deeply different from programming traditional computers. In this Viewpoint, we will consider this challenge, exploring the nature of these differences as well as issuing a call to arms describing open research challenges that need to be met in order to more fully exploit the enormous potential of the global brain.

Privacy management on social media sites | Pew Research Center's Internet & American Life Project
Social network users are becoming more active in pruning and managing their accounts. Women and younger users tend to unfriend more than others.

About two-thirds of internet users use social networking sites (SNS) and all the major metrics for profile management are up, compared to 2009: 63% of them have deleted people from their “friends” lists, up from 56% in 2009; 44% have deleted comments made by others on their profile; and 37% have removed their names from photos that were tagged to identify them.

Information Manipulation, Coordination, and Regime Change
This paper presents a model of information and political regime change. If enough citizens act against a regime, it is overthrown. Citizens are imperfectly informed about how hard this will be and the regime can, at a cost, engage in propaganda so that at face-value it seems hard. This coordination game with endogenous information manipulation has a unique equilibrium and the paper gives a complete analytic characterization of its comparative statics. If the quantity of information available to citizens is suciently high, then the regime has a better chance of surviving. However, an increase in the reliability of information can reduce the regime’s chances. These two effects are always in tension: a regime benefits from an increase in information quantity if and only if an increase in information reliability reduces its chances. The model allows for two kinds of information revolutions. In the first, associated with radio and mass newspapers under the totalitarian regimes of the early twentieth century, an increase in information quantity coincides with a shift towards media institutions more accommodative of the regime and, in this sense, a decrease in information reliability. In this case, both effects help the regime. In the second kind, associated with diffuse technologies like modern social media, an increase in information quantity coincides with a shift towards sources of information less accommodative of the regime and an increase in information reliability. This makes the quantity and reliability effects work against each other. The model predicts that a given percentage increase in information reliability has exactly twice as large an effect on the regime’s chances as the same percentage increase in information quantity, so, overall, an information revolution that leads to roughly equal-sized percentage increases in both these characteristics will reduce a regime’s chances of surviving.
