We're in your browser, watching your gender

This site analyzes your browser history and guesses your sex.  I thought it would have a hard time with me, since I spend so much time on political and financial sites . . . but apparently Bed, Bath and Beyond gave me away:

Likelihood of you being FEMALE is 99%
Likelihood of you being MALE is 1%

Weirdly, my various banks and the Bureau of Labor Statistics are also listed as female skewed sites.  And apparently men never, ever read their evites.
