this script looks at the websites you've visited and gives the likelihood that you are male or female, based on the male-female visitor ratios of the websites.
of all the sites i've recently visited, youtube was the only one with an exact one-to-one male-to-female ratio. google was a close second at .98. npr.org and americanexpress.com also are .98. jezebel.com was 1.02, surprisingly skewed ever so slightly male.
the most male skewed sites i've visited recently were slashdot and sourceforge.net, at 1.74 male-to-female. treehugger.com was up there too, 1.25. mit.edu was 1.13, just between flickr (1.15) and ebay (1.11).
my girliest website visited was hm.com at .57.
the program correctly guessed that i was a girl, with 98% likelihood. if i use my firefox history instead of safari, it guesses 94% likelihood. all of the sites i've visited are pretty evenly split between male and female visitors, with nothing as high as a 2-to-1 ratio. i wonder what the extremely gendered sites are, and how they get this information, anyway. you can check out more web demographics at quantcast.

Since when am I supergirly?
um cool kids don't save their browsing history
