Is Social Media Marketing Heaven or Hell?

If there was a Queen of Twitter it would have to be HarperCollins UK's Head of Events, Sam Missingham (@samatlounge). She pretty much adores - or takes an interest in - all social media, but retains a special affection for Twitter, where she now has some 13,500 followers. As such she was the perfect person to speak at the Frankfurt Book Fair Business Club's session on social media, "Uncensored! Social Media - Marketing Heaven or Hell?" earlier this month.
