Nice looking site and it looks like you have some good info on it.

One suggestion about it that I can offer is to redo your anchor text to internal pages. It will help your SEO efforts if you rename your internal links to reflect what your post is about instead of "read this" or "last post".

As for the monetization, I would put ads on it for things like SEO Elite, Keyword Elite or any other affiliate programs that are useful for BH'ers or people that are into blogging, keyword research, etc...
