I use Newsblur[1] in the browser. The best part of Newsblur for me, is its intelligence trainer.

Suppose you want feeds from website A, but don't want certain stories tagged with "mice", or titles containing "epistemology", and you only want to see articles published by an author named "Joyce Smith", you can do that.

It's pretty great. Reading RSS feeds has become so much more pleasurable. The articles that do make it past the training filters are almost always what I do like to read.
