Writing like a man?

I found an interesting site recently called Gender Genie, which is part of the BookBlog site. Based on an algorithm developed by Moshe Koppel, of Bar-Ilan University in Israel and Shlomo Afgamon, of Illinois Institute of Technology, this program is able to predict the gender of an author. The algorithm uses a selection of words that differentiate between the sexes and is said to be 80% accurate. I tested it and found that it was wrong 4 out of 5 times for me, guessing my writing to be by a male author. Quite a surprise to discover that I supposedly write like a man. Try it out.
