This is an odd little tool that analyzes your browser history to come up with an estimate of your gender. I plugged into it and was told that "Likelihood of you being FEMALE is 3%; Likelihood of you being MALE is 97%," which sounds about right. More interesting is the accompanying ranking of sites I've visited with their male:female visit ratios displayed. The most male-dominated site in my history was NASDAQ.com, which scores a 1.98. The most female-heavy site I've visited was BananaRepublic.com, which scored a 0.63. And the most surprising result was that Jezebel got a 1.02, indicating a slightly tilt towards a male audience.
