How much of personal health info should be online?

The most omnipresent social channels were not engineered for sharing the types of high-stakes information that defines the vulnerability of being a patient. The novelty of sharing personal health information online, even within "private" communities, has not received specific legal attention. As a result, our only certainty is that healthcare-related information that is shared across these channels, be it Facebook or Twitter or online disease support groups, is neither safe nor protected.
