This blog's readability

Hey! You need to be doing postgrad work to understand this blog. Ha ha ha.

Yesterday I was checking a blog where one of the posts showed off the blog's readability. I decided to try it out just for fun for both my blogs. As I already said, this one received a College reading level rating. Curiously, it rated the reading level of my Federer blog as "Genius". I think though that its rather appropriate: you need to be a genius to read about a genius.

I really wonder what criteria it uses to rate a blog or profile's reading level as I've noticed that it gave rather well-written blogs I read a "High School" or "Grade School" reading level. The website does claim that the tool works for most websites.

Still, I'm curious.
