Technorati

http://www.technorati.com/ leading search tool and authority for blogs


"Do you want to make sure your blog is being tracked? Register your blog with Technorati. Do you want to tag your posts to make them easier to find through a Technorati search? Perhaps not your Learning 2.0 blog, but if you owned a business and were trying to attract attention? You'd register it with Technorati.
As a blogger blogger (aka someone who uses blogger.com to blog) you are probably getting tracked by Technorati already - it keeps track of new Blogger blogs by default. But if you want to take full advantage of the service Technorati offers up, you'll need to do this more formally and claim your blog.
And the tagging in Technorati? It is wonderfully easy - you either paste a bit of HTML code into the bottom of a blog post or follow the simple directions you find when you get to the Technorati website. Once one of these are in place, Technorati will pick your tags up when it spiders (or web crawls) your blog." 23 things
