Wikipedia is a joke. So is that idea that any organization can function in a "de-centralized, democratic fashion" without every single member of the "democracy" holding the same standards and values as every other person in the group. It's an ideal, but basically, there will always be people willing to spend more time and energy on a given project than others, and they will always emerge as the "leadership class." The problem there is that if those individuals are assholes. And the problem with this planet is that "the masses are asses." So too is the idea of saying that "anybody can edit Wikipedia." Yeah, as long as your concepts and ideas that you're trying to share are in line with the "democracy," otherwise it's just like any other situation where ideas may have truth to them, but if they're unpopular, they don't get any traction and you're back to square one. Wikipedia is simply the repository for what the mass consciousness deems to be true, but it's relationship to truth varies depending on the level of consciousness of the maintainers of that particular subject.
