Great. I'm not claiming that existing RSS aggregators are broken, but this method is certainly better for me personally. Findka's meant to make things a little more automatic for those who want to spend very little time on managing their sources. The bandit algorithm makes it so you don't need to explicitly mark which sources you've decided are interesting. And the main, non-RSS part of Findka (article recommendations via collaborative filtering) helps expose you to new articles and sources.

This new feature is probably most useful for people who aren't already using RSS regularly.
