I put her four posts written right before the "reveal" post through the first gender guesser I found on Google, and they all came out female. That proves essentially nothing, granted, but this has been studied fairly extensively. If you want to do twenty minutes of work with automation you can grab everything she's ever posted on CopyBlogger and run it through your classifier of choice. Then, heck, run the guys on CopyBlogger against it and see if you peg them right, too.

Natural language processing remains my first love.
