Anyone know any good case studies or reports detailing the benefits (or lack there of) for content websites that add game mechanics (badges, rankings etc)?
The massive drop offs in traffic after the "anti content farm" update to Google's algorithm has been well publicized. This traffic didn't just evaporate, it has to be going somewhere else. Are there any sites that have seen massive gains since the update? I haven't seen any media coverage of Panda update winners.
