I would submit a hypothesis: The capacity of a region for innovation can be measured by the number of formal and informal networking organizations that create "bridging" opportunities across the broadest possible spectrum of society. The richer and denser the skein of bridging networks, the more easily ideas can be communicated through a region, the more spontaneously creative ideas will erupt, and the more speedily people can convert novel notions into business opportunities.
