Seriosity is a pretty cool little company. They are working on taking some of the organizational and reward based systems out of MMORPGs like Warcraft.

They have a product right now in beta that essentially gives people an allowance of email points, and you can use your points to attach value to emails. They have a little flash demo here. The systems reward you for your usage and you can "Level Up" your badges. I find it somewhat compelling. (Though I would be more interested if it didn't seem so Exchange focused.)

They have a short podcast posted that allows you to hear one of the companies spokespeople taking about how cooperative gaming systems management and reward structures can be applied to a cooperate world in a way that's fun for the employees.

Kind of random, but I thought it was pretty awesome.
