I recently listened to Dave Winer's podcast with John Palfrey, and they talked about Top Ten Sources, a site that Palfrey built.

It's mainly about blogs (it seems), and there are editors that determine who the top ten sources of information on a range of subjects. I count 20+ high level subjects, with a handful of subcategories under each subject. I checked out a few subjects, and, while I didn't agree with all of them, they were quite a few I did agree with, and it was a good source for new sites.

Overall, it looks pretty good so far.
