For hyper news nerds, a promising new tool: You sent up your subsciptions, and then filter out the stuff you don't like by clicking 'reject'. It's like a personal Digg for you RSS streams, favorite news sites and blogs. Still in beta, but getting lots of buzz online.

Editorial note: Whoa! You've found a super-old post here on BuzzFeed, from an earlier era of the site. It doesn't really represent where we are anymore, and may in fact be totally broken, but we're leaving it up as a part of our early history.
