Ah, I don't mean "social diseases" as in that euphamism for sexually transmitted diseases - I mean social diseases meaning those which have a community component. To wit: ourhealthcircle.org, a new social-networking site around specific health or wellness topics. Sounds a lot like PatientsLikeMe, which I blogged about last month. One difference is the slightly broader spin of Our Health Circle. My hunch: expect to see lots more of this sort of thing. My wish: that these won't be merely 2.0 chat rooms, but will somehow find a way to compile and use the data.
