Social features are planned. The mobile app is juuuuust about done, and then Search, and a few customizations (mark as unread, oldest to newest, etc). Then I'm going to attack social and get some really wonderful and innovative community features built.

My biggest fear is that the community portion will be too popular and I'll have to find more time than the 1 hour a day I get to spend hacking on NewsBlur. I work on it only in my free time, you know.
