I'd be interested to hear more about this. I think there are some significant opportunities to make cities better (maybe by starting new ones, maybe just by working with our existing ones in new ways). And a lot of the ways technology has changed our lives recently has affected what we need and expect from a city, including things like: - knowing our neighbors - usable mass transit - energy efficiency - interaction with government It's the sort of area that I think has a lot of opportunity in it, but that opportunity isn't clearly something that could make you rich. So as a general area of focus, I think it'd be well worth a hacker's attention. P.S. If you think cities, architecture, and the community shaped by those things are interesting, you should definitely read "A Pattern Language" by Christopher Alexander et al. It illuminates a lot of what goes on in cities and buildings in a very concise way, and will probably give you ideas to improve your home and environment.
