Here is a rant from Esther Dyson, the editor of Release1.0 on Goggle of Blogging, Technorati.
Although the premise of the blog world is decentralized, bottom-up, user-centered content, the value of Technorati-like services is in clustering: helping users to find like-minded people, or unlike-minded people with similar interests.
(Incidently, a little bird told me in IRC that Evan Williams, the founder of blogger.com actually helps Esther to set up her own blog at ETCon few months back).
