Building a website or other polling system that will collect data from people, as much as they put in and categorize and analyze. This will allow for users of the system to search and say 'my elbow hurts when I bend it towards my body'. So the system could share with you how people have solved their elbow problems and with what kind of results. Ie, you could then get users to rate the advice they have received.
So in a sense it's like amazon for ratings. It is so valuable to be able to review what people said about a particular item. It adds depth, brings reality to your doorstep to make a good buying decision. If we have such a system for buying junk, should we have a system to help to take better care of ourselves?
