blogger launched blogger play a few days ago.
i recommend checking it out: it's a strangely beautiful and hypnotic way to watch the blogosphere in real-time. every second there's a new picture: something someone's uploaded to a blog somewhere: babies you don't know, sports teams you don't know, sci-fi drawings by teenagers you don't know.
it reads like a kind of cross between flickr and twitter.
