It's an idea I've kicked around for a long time too. Building a simple Bayesian system would be neat; as you read, you should be able to tag items easily, and in a way that doesn't pigeonhole you into only seeing one side of an argument (I'd like to still see the opposition's view in, say, a political discourse for instance).
I've got too much else to work on currently, but I'd love to see what you come up with :).
