On the Wall Street Journal Health Blog, Anna Wilde Mathews wrote an interesting post about health insurers’ slow entry into social media:

Lots of companies are starting to track social-networking tools like Twitter and Facebook to keep an eye on negative comments, put out their own happier spin and interact with consumers.

But in the health-care business, there are some special challenges because of privacy concerns — notably the federal Health Insurance Portability and Accountability Act, aka HIPAA. Insurers, hospitals and other entities can’t say much publicly about what they’ve done for patients.
