(And anyway, even if you think a professional-to-professional medicine site doesn't have adequate potential users, if we all agree that that sort of thing is what the SE model works for - as opposed to "my father's uncle's friend had a wart that looks kind of like that and he...." - what's the point in not trying to push this one to be the sort of thing we think would work? Or in
creating a separate site that you don't think has enough users?)
