Single-page News Feeder

Google Reader aggregates RSS feeds and Yahoo makes one too (the example is for 3D printing, which I Care About), but you can roll your own at Yahoo Pipes Aggregator (that link goes to the quick video tutorial) or at http://www.planetplanet.org/, which does about the same thing, but for RDF, RSS and Atom feeds, and there’s support for templating of any other kind of file formatting you can think of (if you are a programmer 😦 –but I digress).
