Planetizen has a good three part interview with Bill Bishop and Richard Florida about the future of American cities within the context of their recent books:
Bishop is author of "The Big Sort", which looks at the increasing trend of self-segregation and homogeneous voting in communities across America. Florida is the best selling author of "The Rise of the Creative Class." His new book is "Who’s Your City?", which looks at how choosing a place to live is one of the most important decisions people make, and how people are increasingly moving to places with like-minded populations. We talk with Bishop and Florida about how the trends they’re seeing are affecting cities and people.All three parts together are about a half an hour. Give it a listen.
