Did you know that major celebrities just hang out, talkin’ bout stuff like Twitter? It’s true! Just ask Steve Martin why he joined up: “It’s new to me. I just started yesterday, or the day before. At first I thought, oh, this will be an awful thing to do. And then I actually talked to Tom Hanks, and he said it’s actually kind of fun. So I decided to try it. Now I lie awake at night, dreaming up Twitters. It’s a little bit of a problem.â€
