Today on Smart City we’re talking about communities. Real ones, and the virtual neighborhoods found online in such social networking sites as facebook and meetup.

Phil Wood is the co-author of “The Intercultural City, Making the Most out of Diversity.” In it he describes the advantages of a diverse city, and how the interaction between intercultural groups can strengthen a community.

And we’ll speak with Clay Shirky. He’s the author of the book “Here Comes Everybody, The Power of Organizing Without Organizations.” The book is about the power of the internet to break through old bureaucracy, and how online networking can create brand new ways of interacting out in the real world.

Smart City is a syndicated, weekly hour-long public radio talk show that takes an in-depth look at urban life: the people, places, ideas and trends that affect us all. Host Carol Coletta, president and CEO of CEOs for Cities, talks with national and international public policy experts, economists, business leaders, artists, developers, planners and others on the pulse of city life for a penetrating discussion on urban issues.

Smart City is broadcast at 6 a.m. Saturday and Sundays on WKNO-FM, but it is also webcast and podcast. For the webcast, times for the broadcast in other cities and to sign up for the podcast, visit our website.
