We’ve just put together an infographic explaining some of the motivation behind Symcat! See the full version at http://symcat.com/infographics/cyberchondria.png.
Summary: Cyberchondria refers to the tendency to be concerned about symptoms as a result of searching them online. 4 out of 5 people search online for health information, many of them for common symptoms such as headache and chest pain. Unfortunately, web search tends to rank highly more concerning conditions, even though they’re far less likely. This often causes unnecessary concern among web searchers and even influences their decision to seek medical care. Symcat can help solve that by letting people know what they’re likely to have and what they should do about it by asking others what worked for them. It’s crowd-sourcing at it’s best.
