Blogs and English

I just came across the Blog Readability Test, a cool tool that determines various statistics about the english used on one's blog. This interests me for a few reasons but one in particular is because at some point I wanted to know how many words there were in one of my blogs. I ended up copying and pasting each post into a single Pages document and performing a count there. This tool, among other things, informs us of the total word count in the last 20 posts. I would love to see this tool with a few more options, for instance one to determine how many posts to evaluate and also some way to in bed the statistics in one's blog or web page but for a start it is quite interesting.

This blog's stats can be found here.

Also, take a look at blog of the software's author.

Finally, does anyone know a good way to get a word count or any other tools like this for blogs?
