Thanks for all the good info.
John Boyd is someone whose work everyone should be familiar with.
I just learned of the Cognitive Surplus concept. The instant I saw Clay Shirky's name with that I figured it was worth listening to.
Shirky has a TED video here about it:

Shirky has an interesting talk on TED about how social media has help collaborative groups, like this group on Chief Delphi

An important side lesson on the TED Shirky talk is the Parato Principal, or the 80/20 rule. Think about how the whole system of team performance follow's the Parato Principal, and how we can "flatten the curve" by encouraging and helping teams, sharing knowledge, and just by being super 'GP'.
I don't have the data to back it up but I'd bet only 20% of teams systemwide really pay attention to discussions, draw knowledge from or contribute to discussions on CD. I'm just guessing but I'd bet a box of donuts on it.
