As a physician, I must say this could be one of the first (quoting Steve Jobs) "insanely great" medical apps out there. More accurately, it's not so much HealthTap as it is the concept. Give docs a way to practice and make a living in a "virtual" clinic. Eliminate the excess costs of receptionists, M.A.s, billers, office space rent, medical supplies, office supplies, etc. Let me sell my one valuable asset, my knowledge and problem solving ability (I.e., my brain power) with no overhead cost, in an instantly accessible environment for a very low cost to consumers. It's a win-win for everyone. All they need now is for the world to catch on. If docs would sign up, then patients will follow. They need a few high profile docs to promote it (like Dr. Oz) and it will be revolutionary. Otherwise, it's just a gimmick for geeky physicians like me.
