Whingeing about a patient using Twitter, or revealing confidential information in a flippant Facebook post is a handy way for a doctor to appear before a medical board.
Doctors in Australia have reportedly been reprimanded for doing just that.
But a fledgling doctors-only social network in the US may provide welcome relief to those worried about inadvertent slips on their keyboards.
