Found an interesting little "web tool" that does an analysis of your websurfing history to offer a guess on your gender. Check it out here (scroll down a couple of grafs, and hit the "start analyzing" button).
Despite the fact that I've been known to read an item or two on Jezebel or Perez Hilton, my results came back:
Likelihood of you being FEMALE is 0%
Likelihood of you being MALE is 100%
Statistically emboldened, I think I'll wear a pink shirt today.
