> .. sometimes i think this site only exists to elicit data for various research

hey. i really... don't think so. 'sanity' and 'insanity' aren't established psychological constructs and i can't imagine that they will become so at any point in the near future.

my guess is that... it is more likely that doc john obtained some kind of funding from somewhere or other to offer an informal tool for people to use who were worried about their psychological health.
