You should also be aware of the rules of evidence. This post is really walking the line of slander and I think you might of crossed over it.
The days of posting whatever you want without consequences are over.
Personally, I find the entire idea of defamation, in speech or writing to be unconstitutional... and just plain wrong. What it means in practice is that if you want to shut somebody up, you can sue them, and if they can't afford a lawyer, they're screwed (or they have to take the information down). In my opinion, the best cure for defamation, is to post the truth, and let the public decide. Provide proof, expose the accuser as a liar. Why should the government interfere in what people can, or cannot say?
I realize that this would, undoubtedly lower standards of journalism for the mainstream media, but they write so much bullshit already i'm not sure people would notice much of a difference (or care, if they did). The sooner people start doubting EVERYTHING they read, and start examining evidence, plausability of stories, etc, the sooner they will start to actually think for themselves. As it is, people rely on others to bring them the truth, and although the law is supposed to ensure quality, it doesn't quite work that way in practice.
I'd like to see patent's and copyright go as well. Patent's hinder progress, and copyright can be used to censor.
