I tend to agree with your wife (I'm a 4th year med student at Hopkins), which is why I'm building my own.
I think it's easy for websites to just say "if you are concerned, see a doctor" but I also believe that to be the problem. Obviously, if it were costless (time, money, opportunity cost) people would go see a doctor, but they in reality are weighing those costs. We'd like to make it easy for people to weight the risk vs. the benefits of seeing a doctor.
Moreover, for too many people "seeing a doctor" means going straight to the ER. There they wait for 4 hours (nat'l average) and are frequently told to follow-up with a doc anyway. We want to let others know that there are other options (eg urgent care centers) and let them know when such care is clinically indicated.
