Quoddy is part of the Fogcutter suite of tools for building intelligent applications. It is basically a sort of "mini Facebook"-like social networking interface. It builds on the APIs for social-graph management, activity stream, activity profiling, tagging, etc. It provides the front-end for managing connections and for letting users provide information about themselves, their interests, etc. But unlike Facebook, there are no silly Pirates vs. Ninjas or Farmville applications.
