This guy uses known demographics about the visitors to certain sites to check your browser history and guess your gender. It’s kind of interesting to see the male-female ratio of visitors to some of these sites!
Here are my results:
Likelihood of you being FEMALE is 92%
Likelihood of you being MALE is 8%
