This is particularly dangerous, and I really worry about health sites in general, because if people trust the advice too much, they may not choose to go to doctor (rising health care costs, no insurance, ...) in lieu of listening to advice from the site. Then, when a severe case breaks out, people will spend weeks trying others' recommendations rather than getting a real diagnosis Not to be a Debbie downer, but Im curious as to how you could indicate when a symptom is serious enough to warrant real help. Unless you try a Quora style system (only allowing doctor rs to respond)
