Here's an edited recap of my in-class presentation for the sixth session for the (2009) "Future of Advertising" course at the Minneapolis College of Art and Design (MCAD). For March 2, we advanced a series of Building Blocks sessions--and focused on social media as a "new" building block for marketers. Thanks to Paul Isakson from Space150 and Jim Cuene from General Mills for coming to MCAD to present their insights and expertise on the subject. Much appreciated!
