HealCam is a ChatRoulette variant that invites you to select a disease, medical condition, or health issue (Crohn's, back pain, pregnancy, bipolar disorder, allergies, HIV, etc) and connects you with someone else who shares your problems, so you can share notes. Sounds like a helpful way to find tips and commiseration when you need it.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
