Deus Absconditus Fever is a self-hosted RSS feed reader. It works like a traditional reader, but also sorts news feeds based on hotness -- wherein links that have the most links on other sites (or within your own feeds) get more prominence on a temperature scale.
This is a pure web app, and it is optimized to run on mobile or in the desktop, though some third-party apps (including Reeder for iPhone) support accounts as well.
