technorati?

not really sure what this entails, but i got an email suggestion to join Technorati so that the "spiders" can be released?
anyway, still new with all these cool things you can do with a blog.
back when i had my old one, being on blogger seemed like the neatest thing! but now, oh boy! there are just so many possibilities of making your blog just a little more cooler, a little more catchier, and blah blah blah =)
so the point is, i've decided to join Technorati and see what the hype is all about!
