No, I haven't :-) What sort of responses do you get? Could you please list some?
(I find myself in the position of being the only guy who has root and cares to do site admin on the server hosting Lemonparty (Wikipedia explanation). I found a few other shock sites hosted there too when I did a cleanout of dead accounts. It's slightly disquieting to find myself responsible for maintaining this species of cultural icon.)
Note that some of these responses are from people who derive pleasure from subverting expectations.
My various interweb browsings stumbled me upon a potential Cockatrice in written, philisophical form. I've thus far read through the first chapter, and it is less anti-rational than most philosophical writings.
I'm reading through it right now, and will provide my feedback when I'm done, likely as a front-page post.
Personally, I'm a Fatalist, with some sort of Weird Soldier Ethic, who plans to go out the same way that Hunter did (if the cops don't get me first), but I've got a bunch of nonsense to Write first. I figure that'll make me somewhat immune. That aside, I doubt it's a real cockatrice - or we would've heard about it before.
It is a strong exercise in Nihilism. So, with those cautions given, I offer it to you: an extensive suicide letter.
Tip of the hat to this guy.
