Twitter is a pretty tough thing to grasp for Your Mom and celebrities. Seriously: we have a theory in which Twitter is ultimate litmus test for intelligence. If you can't manage to write a single sentence coherently, you're really in trouble. So why are so many famous people, including Columbia University graduate Julia Stiles, so incapable of understanding how Twitter works?

Stiles joined Twitter this afternoon and has been pretty busy so far. Like most celebrities who use Twitter, she has spent the bulk of her updates communicating with other famous people. Perhaps this is how celebrities want us to see them: it's one big club of bold-faced names, chattin' it up because they are all such great friends. But not the kind of friends who can just email each other privately or text? In any case, Stiles immediately asked Mia Farrow for advice on how to work this contraption: "Mia-Is this private? I think I need to take some kind of twitter tutorial! How does this whole following&followers thing work? &what's FF," she tweeted without actually including Farrow's Twitter handle. And then she said hey to Joel Madden, Gennifer Goodwin, Destiny's Child's Michelle Williams, and Vanessa Carlton. (What a weird / amazing book club they could all form!)

"Guys, it's my first day please be gentle/kind! I am trying!" she wrote this afternoon, so we'll try to take it easy on her. At least she's not outsourcing her Twitter account to some publicist's intern or an assistant. But GET IT TOGETHER, girl!
