I don't care about a web service; an RSS feed would do (and do better, since I can't be bothered with all the overhead a web service entails). MemeStreams is a system whereby members rate items and where the items displayed on the front page are an aggregation of those ratings. Unfortunately, as Michael Feldstein notes, you have to be a member to take part (note well: somebody will eventually discover that ratings can be syndicated as well, allowing such systems to be distributed, as I have described in several papers).
