Pro News Feed Optimization
Although Prismatic has a fantastic design, its biggest differentiator from the competition is its best-in-class algorithms that determine what goes into your news feed.
When you initially sign up for Prismatic you link your G+, Twitter or Facebook feeds which it uses as initial indicators for the topics you're interested in. You can then edit the list or add topics it missed. You can also directly add and remove sources such as the Times.
As you use the app it continually gets more accurate at predicting the news you're interested in by monitoring how you use the app and allowing you to mark things as "interesting" or "not interesting".
