AmphetaRate sounds a bit like BuddyBuzz:
AmphetaRate is a centralized ratings/recommendation service that provides personalized news and blog recommendations through a news aggregator interface. Using compatible aggregators, you can rate articles found in your subscribed feeds to discover articles and feeds that suit your taste, thus filling your news addiction.
This service is most useful for people new to RSS feeds and for news junkies who cannot afford missing any important news. Indeed, with thousands of blogs and feeds out there, how can you be sure you are retrieving all the pertinent news? AmphetaRate solves that problem.
