I think you're right on both counts--once the spotlight shines on a condition, people start to see themselves in it. It's just like the psych students who are notorious for coming down with everything they study. ;) But it's also good to get the resources for people who need it.

And of COURSE internet quizzes are completely foolproofily accurate! It's just that my IQ shot up 30 points between taking the quiz on one site and taking the one on another! In three days! The internet NEVER LIES.
