Feedmil: a long tail search engine for RSS feeds

Feedmil is a search engine for RSS and Atom feeds based on the concept of the "Long Tail." Basically, the idea is that small, obscure feeds have an audience as long as the interested people have a way to find them via search technology. So, instead of just entering search terms into Feedmil, you also select a popularity range, anywhere from the obscure to the well-known.

By filtering your results by popularity, you'll be able to pare down a bunch of results that are presumably all relevant into the top sites on your topic, or some surprising ones you might not have heard of. Feedmil really does seem to be an effective way to fill up your RSS with new content. I'm not sure what kind of search algorithm they use, or how they index feeds, but the results are certainly high-quality.
