Bottlenecked Blog Readability

I've posted before on the personality type of this blog. But recently Justin Landwehr posted on one of Google's new advanced search features. It allows you to see and filter your search results based on reading difficulty. Which also means you can check to see the reading difficulty of your own writing. Here's the results for the Bottlenecked Blog:

I'm not exactly sure what to make of this. Compared to other blogs I read I am above average. A part of me is happy. Everyone likes to be told they have a high reading level. Even though the topics discussed here may be a factor, the sites that are blockquoted probably are too. And reading level doesn't necessarily imply intelligence. It's also possible that Google just couldn't get a good read on the site and just gave it an intermediate score. So what really matters, readability, probably isn't measured very well with this tool. Good thing there's another tool that let's me measure that, the comments section. Please let me know how this blog can be made more readable, even if the answer is better grammar.

To use this tool yourself click on advanced search on the Google homepage, and select "annotate results with reading levels" under reading level.
