Somebody thinks that this blog speaks to an educated audience. What is the readability level of your blog? I ran into this fun (stupid?) little thing thanks to Tim Stahmer (and his blog aggregator). Take the The Blog Readability Test for your site.
For the record: Desire2Blog = college undergrad, Free Web-based Tools = high school, Online Student Satisfaction = high school, Sign Language = junior high school. Apparently I appeal to all levels in one way or another.
