I use the 'recommended items' feature on Google Reader quite a lot. It does a good job of finding things I'd like, but also puts in a lot of other random stuff. (Which I occasionally like.) The more things I 'liked', the more random stuff appeared... (Probably because I have such a diverse set of interests that it just can't read me well.)
