Medicine in the Age of Twitter

Dr. Pauline Chen poses an interesting question in her NY Times article, Medicine in the Age of Twitter: Does online social media help or hinder patient-provider communication? If you haven't heard about Twitter, it is a new social media platform that allows users to communicate via short, 140 characters or less, "tweets" to other users. I am intrigued about the possibilities of connection, but am wary of the lack of human touch. What do you think?
