Psychiatrists want perfect isolation, so that they can treat everyone from far right nuts to far left nuts to plain unsalted nuts. The only way to do that would be to publish nothing, and surely you must agree that at least some psychiatrists must be cursed with good writing skills and something to say.

I'm all for anonymous publishing, I think it's a powerful and useful.

Retconning SSC as an "anonymous" publication is silly, though, and really dilutes the efforts of people who truly want to or need to remain anonymous.
