Of course, our blog is written by a variety of genders, but all the same we stumbled across GenderAnalyzer.com and plugged in our blog address. See the results here. Sticking to the binary, I see.
"We created Genderanalyzer out of curiosity and fun. It uses Artificial Intelligence to determine if a homepage is written by a man or woman. Behind the scene, a text classifier hosted over at uClassify.com has been trained on 2000 blogs written by men and women. In our lab it seems to works pretty well, we want to see how it performs on the web! We hope you like it!"
