The biggest problem that I have with Wikipedia is not the concept it's the utterly inconsistent, ludicrous, arrogant "we're
special" attitude of the Wikemedia Foundation. Dammit, when you're served with a lawsuit, you have an obligation to at least communicate with codefendants and their counsel in the same lawsuit, even if your position is that you are/should be immune from suit.
And then there's the Scalzi Incident. Admittedly, I find the source relied on by Scalzi to be unusually reliable. But then, I work with authors, so that's measuring outliers...
This kind of arrogance that Wikipedia is new/special and shouldn't be bound by anything "traditional" undermines everyone. Grow up, and realize that "different" and "new" isn't always "better."
