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.
