I find this and your last post hang together in my thinking. I'm a great fan of Hagel et al and I've imagined an edge place where there is exposure to many other edges. A cognitive ecology that supports serendipity for edge thinking. I often visualize an artsy area, because artists are often people who try to push the boundaries out to new areas, new edges. Not artists as traditionally understood, but anyone pushing on the edge. My idea of a brick and mortar PKM space. The problem is that there is no way I can think of that would support the monetization of such an ecology, at least without new way of thinking about jobs and maintaining living standards.
