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! Bruce Larson
