Feedrinse

Ok, Feedrinse is really cool if you're getting sick of sifting through hundreds of posts to get a few nuggets. I think you can create up to 5 keyword-based feeds from pre-existing feeds, and if this actually works well, I'll be a happy camper. I've created a keyword-limited feed from DocuTicker, for example. I'm going to try it out on ResourceShelf now.
