HealthTap is a community of doctors and clients seeking answers to health questions. Its central service provides immediate access to doctors and their knowledge either by doctors answering client questions in real time, or through a large database of previously answered questions and answers from doctors that are peer reviewed and tagged with recommendations by other doctors. By combining the doctors’ recommendations with data provided by each client on himself or herself, HealthTap provides customized results to queries. In this video, HealthTap CEO Ron Gutman explains unexpected lessons they’ve learned from offering the intelligent search service.
