A community-driven medical diagnosis platform where anyone can describe the symptoms, upload photos/videos, medical paperwork, then have the community discuss and come up with the most plausible diagnosis.
To motivate a fast response, the person that requests the diagnosis could add a bounty for whoever first comes up with the correct diagnosis.
I've found a few attempts at creating something similar, but they don't seem to be what I had in mind. Ideally, it would be something similar to brainstorming.com or Quora only with a different purpose.
There could be a panel of experts that rate each response, then based on the ratings the person's future opinion is higher/lower valued. It would also be great if the people asking for diagnosis came back and gave feedback after their problem was solved.
This could be a game/practice for medical students. The panel of experts that oversee the responses could then be seen as mentors.
The value of such a platform would grow with an increasing user base. It would be a goldmine for pharma-related companies to advertise. Ad revenue could pay for the experts/reviewers.
