The social and the anti-social networks

Why go to an entertaining movie when you can listen to an informative radio program? On today's "To The Point," we discuss the rise of online social networks, starting with Facebook, and consider the ways our logged-on lives are changing society and culture. With Judith Donath of Harvard's Berkman Center, Walker Smith of The Futures Company, Fred Vogelstein of Wired, and Michael Kaiser of the National Cyber Security Alliance. Listen to the show here.
