Power Law Blogs

Clay Shirky wrote an article that observed, in effect, that the popularity of blogs -- as defined by inbound links -- will be governed by  who links to whom. Where popularity breeds popularity, this will have the effect of "clumping" popularity (inbound links, or attention) around a relatively tight set of interconnected blogs.

Some examples of high Power Law blogs:
 * BoingBoing
 * MetaFilter
 * Instapundit

Naturally, there are Power Law winners in the various blog categories, as well.
