Although I can't say that I'm working on "creative communities," they 
are definitely on my radar screen as I have, through my campus 
responsibilities, become very interested in groups.  This area seems 
very promising from a history of economic thought perspective.

Here are a couple of sources that might be useful:

Michael Farrell, Collaborative Circles: Friendship Dynamics and 
Creative Work (University of Chicago Press, 2003);

Keith Sawyer, Group Genius: The Creative Power of Collaboration 
(Basic Books, 2007).

Somewhat more distant would be the work of Richard Florida.

I've read Sawyer and thought that his work provided an opportunity to 
rethink "schools of economics"--I especially have Schumpeter in mind 
here.  Coupling Sawyer's ideas with the ever-expanding role of 
technology in the development of collaborative communities present 
some interesting possibilities, both from the perspective of the 
history of economic thought and the rest of the discipline.

I hope this helps!
