Facebook And/Or LinkedIn For B2B Marketing?

This is a clip from a Minnesota PRSA core training event we hosted a while ago at Tunheim Partners about social media for B2B marketing. Mark Palony (who blogs at Wondering Out Loud) and I were the speakers; this particular clip, courtesy of Kasey Skala, features our reaction to a question about whether to use Facebook for business communications.  Found at YouTube from MinnesotaPRSA.
