The "Gender Genie" determines sex of an author based on keywords

Check out the Gender Genie.

Feed it a big chunk of text from your blog or whatever, and the Gender Genie should be able to identify you as a male or female, using keyword analysis. Pretty whack idea, but it correctly identified me as male. It looks really simple, too. Apparently, using the word "with" a lot pegs you as female and using "around" a lot means you're male. Who knew?
