Total # of WP Blogs Statistics

I had written a small crawler to count the total number of WordPress blogs that ping Weblogs.com and BlogRolling.com. It looks at the meta tags in the blogs to determine the version and tool used to build the blog. It has unearthed dissappointing results (so far). Matt (and others) have suggested heuristic methods and other means to make the determination and I will be implementing them in the future. In the meantime, here are the most recent stats:

total blogs crawled: 58641
total wordpress blogs: 216
total Blogger blogs: 16113
total Typepad blogs: 1549
total .Text blogs: 323
total BlogTool 1.4 blogs: 262

I was really hoping to find more blogs that are run by WordPress. I have a sneaking suspicion that a lot of WordPress blogs do not have the original meta tags from the index and are thus not responding the way they should. In order to circumvent this problem(while I come up with better heuristics, any help is appreciated there as well), I would really like to solicit some help from the WordPress community. If you are a blogger and your blog is using the WordPress application (any version) please click on this link, type in the url of your blog and click on submit. If your blog url is already in the database, it will make sure that it is recognized as a WordPress blog and will show you the list of WordPress blogs crawled so far. This list can be used for publicity and for various other WordPress related issues and statistics. Thank you for your participation. Here is the link to the stats page:
