The main thing I remember about Shanadeus was that, by the end, I was no longer able to tell whether the poster was trolling, or whether the attitude was one of disenfranchisement and a sense of self-importance with being the last sane person in an insane world. There was always a sense of self-importance in seeking some intellectual high-ground, but I couldn't discern whether or not it was just an internet persona or how the person really was.
Just one of many trivial internet mysteries that will remain unsolved because I'm either not smart enough or not invested enough in to keep digging. I'd like to say it's the latter, but some may disagree. C'est la vie.
But as to whether or not Shanadeus should have an account here or not, I fail to see the harm. After all, anything that's out of line with the totalitarian regime here will surely get smacked down by the strong arm of bork laser.
