The Craigslist Craig addressed the Association of Alternative Newsweeklies. Lots of good stuff in there, if you have the time to read it. I’ll be interested to see whether the effort at collaborative filtering to which he refers fares any better than the countless others. (ThirdVoice may not have been collaborative filtering, strictly speaking, but it was an idea I had also had, and would have needed something like collaborative filtering in order to be useful)
Or maybe what I want isn’t really collaborative filtering so much as delegated filtering, or maybe it’s the same thing, and it all gets into trust networks, I imagine.
