Wow, way to stereotype.
I would bet that most relatively young computer-literate people in the medical community know about this forum and lurk here at least once in a while, if they dont post. Maybe not for a social life, but for advice, bouncing sensitive issues around for input in an anonymous way, and just getting opinions from peers or people who have already been through the process.
I wouldn't put it past selection committees to peruse the forums during key times of the year. If it's not an official representative, the medical community is amazingly small and word gets around fast. Dont delude yourself. I've seen it happen (in connection with SDN).
