Of Twitter and Tweets

If you are not on Twitter I think you should be. Why? It's fun. Follow some famous people you have heard of and read thoughts and opinions (generally) unfiltered by agents, publicists, and the like (though I'm sure quite a few "stars" have people tweet for them). But where else, where else I ask you, can you see a picture of Danny Devito with a piece of the Berlin Wall tied to his foot with an iPhone cable?
