Social currency is shared information that encourages further social encounters. It’s not a new concept, but the social web increases its prevalence. In the web-based collaboration software platform called Rypple, a simple act of thanking someone on a team and using a badge as a way to show your gratitude is a form of social currency. A platform called Badgeville promises to add virtual rewards to your digital media property through leaderboards and virtual “badges” that act as reinforcements to reward certain behaviors and encourage others.
I see a world of games, competitions, fun to be added to online communities using social currency platforms.
