In this video of a talk at the Columbia University Business School, Zeynep Tufekci discusses how the Internet was used by activists in the Middle East to document corruption and abuse and to coordinate with each other in the public sphere during the Arab Spring uprisings. Zeynep, a professor at the University of North Carolina-Chapel Hill and a fellow at the Berkman Center for Internet and Society, is one of the founders of the NOWAR Collective (forerunner of the Third Coast Activist Resource Center). Her blog, technosociology, is a great read.
