One of my most recent projects has been a cross-cloud effort with my colleague, Megan Hoagland, to unify our the signals and scores for "levels" of influence/expertise/etc. across products like Chatter, Chatter Answers, Q&A, and Communities into a single, unified global reputation score. This single score will be able to allow you to get an "at a glance" understanding of who a user is and what they are good at. The idea is simple; a customizeable set of core cards made of like signals that collective roll up to a global summary score. So if you have a score of 95, you're an expert and a single tap will reveal all the info that went into that score. This design is currently in the iteration phase of the design process. Overall reaction has been very positive across clouds and PM has already begun to roadmap the dev efforts.
