*Tweeting the Revolution: agency, collective action, and the negotiation of risk in a networked age* ** http://cyber.law.harvard.edu/events/luncheon/2011/10/coleman Beth Coleman, MIT Oggi alle ore 18.30 Webcast live: http://cyber.law.harvard.edu/interactive/webcast oppure: http://nexa.polito.it/berkman-webcast-live /From Beth Coleman:/ "This paper looks at the impact of social media platforms on collective action. In particular, it focuses on spheres of activism where personal risk (bodily or otherwise) is the condition of participation. For this analysis, I discuss interviews conducted with Egyptian activists around the events of Tahrir Square. Issues of copresence, witness, and visibility are central to my discussion. This talk is based on a research paper developed with my coauthor Dr. Mike Ananny".
