julian assange, the wikileaks founder, was one of the finalists. the tea party was one of the finalists. who else? >> i quite like the way they have the miners on there. in terms of global impact. look at the chilean miners story. most people i know probably lived that story through the prism of facebook or twitter. it's not the same as facebook in the sense that you don't actually have to have a friend, they can just be a follower. it's very interesting i'm now getting my news on a kind of constant stream from a social networking platform. and i'm getting it very, very fast. i can react to it. i can communicate my thoughts to it to the world which is quite useful if you're presenting a show on cnn for example. i also see friends of mine engaging in this thing who want to have a voice, who want to have an opinion. in the end, everyone's entitled to an opinion.
