recently blogged about the Gender Analyzer
that will analyze a blog and guess whether the author is male or female. Its accuracy leaves something to be desire (according to its own poll, it guesses right about 57% of the time) and it gives no insight to what leads to its conclusions.
I was must more impressed with the Gender Genie
, which not only did a better job of guessing my gender, it provided details on why it guessed that way.
