Clay Shirky: How cognitive surplus will change the world

Another interesting TED talk from Clay Shirky on how “cognitive surplus” - the shared, online work we do with our spare cycles is something that, if harnessed correctly in our society - will help to change the world for good.  He also talks about what drives human behavior (personal reward/cost vs social constraints) - and how not to motivate people to do the right thing.

I’m certainly a believer in the power of the ‘social contribution economy’.  Well worth a watch.
