SocialRank – The Voice of Community Has Spoken
http://www.socialrank.com/

SocialRank monitors thousands of blogs in popular categories and identifies the hottest stories, bloggers and posts of the day. They do this democratically by measuring what stories users link to, talk about and pay attention to. The result? You now know the hottest stories and blogs in your favorite fields. Browse, learn, enjoy, and most of all participate. It’s really quite addictive ;-) This has been added to my Bots, Blogs and News Aggregators presentation resources page.
