I called Slavin and asked him to imagine how gamification might evolve over next few years. He predicted that gamification as a buzzword would eventually lose its luster. "The idea that gamification requires certification programs and specialists and O'Reilly books— that is going to fade away," he said. "Still, there are real things, valuable things" we could take from gamification and incorporate into the design of, say, Facebook, or a new fitness gadget. In the coming years, he said, e-commerce sites will probably continue to incorporate various aspects of gamification, from VIP points to tangible prizes. Our social networks, too, are likely to become even more gamified, with users competing for rewards, badges and, of course, the approval, in the form of a small upheld thumb, of our peers.
