I love all 5 of these TED Talks about where ideas come from. My favourite though is Steven Johnson’s.
Where are you building idea incubators?
How many coffee shop (“liquid networks”) kind of environments exist in your organisation?
The idea of exchange put forward in Matt Ridley’s talk very insightful too. Exchange is of course what happens in “liquid networks” and is a key to collaboration.
Be the difference you want to see in the world.
