1) She plays World of Warcraft. I'm not saying that's the best game in the world or anything, but I play it, and I'm a strong believer that most hot chicks play it and possibly do so completely nude. In the shower.
2) She shows up at conventions, in Slave Leia gear.
3) I feel as if, if she is a nerd and not faking her inner-geek to exploit those who give her exposure, then she really is some kind of champion of geek vagina. Bloggers, webmasters, choice-makers, and nerds everywhere love the pictures like the ones above because it gives them hope that hot chicks do really like to be nerdy.
4) She is almost always on twitter showing her boobs.
