I was intrigued by the site linked at the beginning.

I went for the upload anonymous text option, and it was... interesting. It does appear to be a legit tool, though how useful is another story.
As for myself, I chose two posts from here. Both put me in my 30's (34 and 36), which is wrong (44). However, the first post had me at 88% feminine. The second had me at 56% masculine. I thought that was kind of amusing.
