Social media has two faces

Very interesting blog post points to some of the problems with social media for marketers (and the rest of us). Sure, it can really help a product, but it can also really hurt if some in the "community" turn against it. It includes research showing that people who are most involved with a product by, say, commenting on it or interacting on a web site, are the most knowledgeable but also the most critical of it. Nice to have something to think about the day after Thanksgiving.
