Dispatch From The Twitter Revolution

Greetings from Shanghai. I don't think you're on twitter, so I thought I'd give you a head's up on something pretty amazing. The hashtag #CN4Iran - designated by Chinese twitter users offering support to the Iranian uprising - is a trending topic on the twitter top 10  of trending topics. Ahead of Avatar, Singapore Idol, and Sezairi. Needless to say, twitter is blocked in China (though easy enough to get access to it). An absolutely incredible development.
