I came across a very interesting article with a set of network maps of the 101st (1989 session), 107th (2002) and 113th (2013) Congresses. From the article published in the Economist:
"The network maps shown here look at the degree to which senators vote the same way. Each node is a senator. Links represent instances when senators have voted similarly on substantive legislation on at least 100 occasions during the same congressional session. Their placement is determined algorithmically, based on their co-operation with other legislators—which has the effect of pushing more bipartisan ones to the centre."
The conclusion of the analysis, done by a computer science undergrad at Harvard, is not surprising; Congress and American policymaking has become much more polarized over the past two decades.

Pablo Barberá and Megan Metzger, graduate researchers in the NYU Social Media and Political Participation (SMaPP) laboratory, report on the use of social media by Ukrainian protestors.
"Taken together, our data suggests that Ukrainian social media users are strategically using the tools available to them in the ways that seem most effective. The disparity in language use between Facebook and Twitter suggests an understanding on the part of users about the audiences consuming the content they produce in each medium. The spike in Twitter use is, to our knowledge, a previously unobserved phenomenon. It suggests a reciprocal relationship between social media and protest, where social media can serve as an important strategic tool for protest, and at the same time attract new users to online communication platforms."
