Have you tried the Gender Analyzer? You punch in your website and it tells you if it is written by a man or a woman. Obviously it doesn't work; why else would it think I was a woman? (66%).
Along the same lines, have you tried to seel what level of education your blog is written? Try out the Blog Readability Test. Mine is at the high school level; I thought it might be lower.
Last link. Have you seen Santa's Gmail account? It's good, but he may not be.
