Read this if you're a genius

I stumbled across this tool that claims to determine the reading level of any blog you give it. It’s kind of fun to try various blogs and see what you get. What is this blogs rating? “Genius”. I imagine that the algorithm just takes the words in your blog and compares them against a reading-level chart, but it does seem to match up at least somewhat to my impressions of certain sites. Of the sites I’ve tried, this is the only one with a genius rating. For some reason that kind of makes me feel good, though perhaps I should be taking that as a hint that this blog is too hard to read. Comments?
