This means that while anyone can edit an article, almost everyone gets their edits reverted.
In over 10 years of editing, I've never come across an issue that couldn't be solved by one of the above methods. If you think there is some article that is having a problem, please post it.
Their are cabals that require extreme investments to fight. Most people aren't willing to put in that investment. Much the same that many people who face discrimination don't take it to court because they don't have the resources to throw at it and the expected return is too small.

There is something like that: Conservapedia[0]. Reading it is fairly infuriating. Mostly because it is so extremely one sided and trying to argue an agenda in every single article.

We barely trust our governments and our bosses' bosses. Not all of us live where we can trust our news. I know a lot of us on HN are business- and libertarian-minded, but we should recognize that places on the web like Wikipedia are special, and for all of us.
There is no trusted source for everyone. Anyone with a bias they can't get into Wikipedia is free to spread FUD on the egregious nature of its biases and misinformation.
