We recently returned from a one day Gamification Retreat hosted by our game mechanics partner, BigDoor (thanks Keith, Jeff, and team!). Lead by online community and social gaming expert Amy Jo Kim, a lot of great ideas came out of the group discussion and EVO Media Group's CEO, Geoffrey Nuval, recently put his notes up on his WebHub.
