Blog + Portal = Blortal = Meta-Blog

One of the roots of blogs was in the lists of interesting sites for a particular field. But blogs are now so numerous that we need metablogs - lists of blogs within a particular area. Here's one, offering a fine collection of academic blogs, arranged by subject in a wiki. It calls itself a portal, though blortal might be more appropriate.

First Meta-Blogs, Now Meta-Podcasting...

I can understand why there are blogs about blogs, but podcasts about podcasts? Where will this meta-madness end?
