At a time when we are all connected by social networks and we watch revolutions unfold on Twitter hours before they’re splashed all over TV news, it’s easy to assume that the only thing a movement really needs is the Internet. The truth is actually much more complex, as Evgeny Morozov illustrates with the help of some cats and mice.He gives some background, then discusses online debate in politically oppressive countries at 3:50. But he shocked me right after the five-minute mark. You need to know how some governments are using the Internet to track down activists and dissenters. There are no cookie-cutter approaches to changing the world.
