If you haven't gotten into Twitter, or don't understand what it's good for, that's actually a good thing, because here's the thing about the people who love Twitter at first sight: They are narcissists.

That's why celebrities love it. Of course, there is an upside to all this narcissism. You get tweets like these featuring Adrianne Curry topless pictures. Here's your classic narcissistic attention whore, but she is hot. And topless. So there's that.
