In this TED talk Seth Priebatsch is forecasting that, after topping the world with a social layer (read: Facebook) in 2000-2010, the new decade of 2010-2020 will top the world with a gaming layer that will enable people to actually influence the world. 

In short, this video mentions four important game dynamics to enable this to happen, which hold tremendous potential for social and collaborative learning (games) as well:

1. Appointment dynamics, like 'happy hour', that reward persons by doing something at a certain moment in time. For education this could be attaining a group meeting to discuss or get information as incentive.

2. Influence and status, like the color of your credit card. For education this could be achieved by adding levels in  a course or game that come with certain benefits.

3. Progression dynamics, like the percentage of completion bar in your LinkedIn profile. For education this could be to see eachothers progression on tasks you work on together.

4. Communal discovery, like the Monopoly game where you have to collaborate to achieve something. For education multi-role playing games where player have to complement eachothers knowledge are thinkable.
