- The Nearest Neighbor News Network (NNNN) is a collaborative filtering RSS aggregator. NNNN collects articles from news sites and weblogs of your choosing and then displays them all together. It also displays other articles that it believes you would be interested in.
It doesn't learn from what you read like Findory. You have to tell it what you like. It's more like a version of Bloglines that focuses mostly on helping you discover new weblogs and news sources. It's a very cool idea, an interesting step toward a next generation weblog reader.
Unfortunately, it's slow as a dog. The trick with personalization is providing high quality recommendations to hundreds of thousands of users in a fraction of a second. Not sure what algorithm they're using, but a simple implementation of collaborative filtering breaks down pretty badly with only a few thousand users. I suppose that might be their problem.
Anyway, it's a great prototype, a good demonstration of what a simple, easy-to-use, mass market weblog reader could look like. Worth a look.
