Gender Analyzer claims to be using artificial intelligence to determine whether a given blog (you provide the URL) is written by a man or a woman.
For each of my blogs, the response was that it was written by a man. This does not surprise me; for years on UseNET many people (mostly men) assumed I was a man. Apparently I have a writing style that is interpreted to be male.
The blog also requests that you indicate whether the response was correct, and lets you view the breakdown. It's doing just barely better than random: 56% correct, 44% incorrect.
Try your blog at the link. What did you get?
