While news from Iran streams to the world, Clay Shirky shows how Facebook, Twitter and TXTs help citizens in repressive regimes to report on real news, bypassing censors (however briefly). The end of top-down control of news is changing the nature of politics. (Recorded at TED@State, at the US State Department, June 2009, in Washington, DC. Duration: 17:03)
We read a lot of Shirky's stuff at uni, and i just think he's fantastic. If nothing else then for the way he presents things and the way he talks. Have a look.
