There's not a big pool of well-adjusted people who are equally willing to learn the intricacies of Wikipedia and manage it better. The people who care a lot, in the wrong ways, outnumber people who are passionately neutral. Most people don't care enough to fight bad edits and reversions. They just stop contributing. I know I did. (I wasn't even editing controversial areas, just adding to data about chemical compounds.)

I still love Wikipedia, but mostly as a starting point to find deeper references. (Which, to be fair, is primarily how you should use an encyclopedia.) The degree to which you should trust it as your sole starting point for research in an unfamiliar area is anti-correlated with the length of the article's Talk page.
