I decided to build my own RSS reader a few months back after getting into the habit of consuming news via RSS, and not really being thrilled with any of the readers out there. The source is open and can be pulled/built locally from GitHub[0] or accessed at the public instance for free[1]. It also made it to the front page of HN through a Shown HN post a while back, so at least a few people here enjoyed it (:
