Audio of Keynote 2011 SXSW "The last decade was the decade of social. The coming one will be the decade of games. .. What comes next is another framework, not another social layer, but a "game layer". And it'll be even bigger. Instead of trading in social connections, the game layer traffics directly in human motivation. It's not about the number of followers you have, or how many people "like" you, but about how you can leverage game mechanics to achieve all sorts of great things. Use them cleverly and they can enhance education, empower local businesses and make your life more fun and more rewarding."
