When you talk about gamification, do you mean things like perks based on reaching "levels" like myself and @beanz have made posts about? I wrote a little web page to show people what "level" they are at but it's not in a presentable state yet (totally functional, but raw). It's based on the same way that levelling works in games like World of Warcraft, marginally increasing costs for each new level. I think something like that would be a great reference point for providing perks, again like in World of Warcraft where your level allows you to use new skills, equipment, take on new jobs etc). Are we thinking along the same lines?
