Technorati

So, I've heard a lot about Technorati. In my quest to deeply understand blogging and SEO, I've signed up with them (it's free) to see if my ranking jumps at all.

Here's a bit about Technorati:

"Currently tracking 112.8 million blogs and over 250 million pieces of tagged social media.
Technorati is the recognized authority on what's happening on the World Live Web, right now. The Live Web is the dynamic and always-updating portion of the Web. We search, surface, and organize blogs and the other forms of independent, user-generated content (photos, videos, voting, etc.) increasingly referred to as citizen media."
