This site claims to be able to tell the difference between a man and woman just from how they type. It seems pretty inaccurate. I think some of the things that are calculated as a feminine trait are probably unisex because I keep getting female as an answer even when I paste in mens' typing.

It thinks mrquackers is female after three different excerpts from him. And Hal is 1/2 times female.
What does it say you are?
