Signal to Noise

I love using my aggregator to stay up-to-date with all the goings on at the various websites I read regularly. Unfortunately, many many websites cross-post the same items. I’ve recently begun reading Gizmodo (I went to high school with the editor!), and I’ve been increasingly annoyed at the number of items first posted there that then proliferate on to BoingBoing or Slashdot. Both BoingBoing and Slashdot have enough new content to make it worthwhile to continue to subscribe to them; but I really wish that this Web 2.0 craze would find some way to keep me from reading the same story on three different sites in my subscription list.
