2479 What's wrong with this picture?

Technorati today says there are 39.9 million blogs, so let's just say 40 million. And I am ranked 2,523, but I'm not in the top 100,000. OK, I can handle that. I don't think it has a way to track all seven of my blogs together, and even blogger.com gets that number wrong, showing something like 9,000+ posts when I can only find about 3,500. But here's a strange thing. Technorati has a little chart that tells how many posts you have per day. This chart says I posted 15 times on May 11. Now that was Thursday Thirteen, but there were only 3 posts. It doesn't count comments, because there were 40. So what is it tracking?The number one blog on technorati is in Chinese. They have a few billion head start on us. There are some gadget blogs doing well like Gizmodo and Lifehacker. Left wing bloggers have spawned, regardless of what they say about the right taking over the country. A couple of blogs I link to are in the top 100.
