“Brooklyn Doctor Opens IM Practice: OMG! You’ve Got Cancer :(“
(wired)

This guy rocks. He’s not only one of the few innovative doctors but also a kickass photographer.

He’s available via IM and E-Mail and doesn’t have a practice or a secratary (thus keeps overhead extremely low!). He only does house calls. There is other stuff he does different from conventional doctors. Check out his website.
Love the concept!
