Technorati where blogs rule but I have no Authority

After joining Technorati, claiming my blog, setting up some favorites, and even importing my blogline feeds, I still didn't quite understand what Technorati is for. Why Technorati instead of Google, Yahoo, del.icio.us or Bloglines? I finally looked it up in Wikipedia.

Here's my take on Technorati's purpose: You can search for information on blogs, specifically their tags, knowing that results will not be cluttered with hits from websites. If I'm right will someone let me know?

I just don't see myself spending much time here. If I do go back I would probably use this search instead of the standard one.
