Everything that people say about StackOverflow and its "deletion culture" is doubly true of Wikipedia. Wikipedia today is rigidly controlled by a relatively small group of power users. It's completely unusable for any "culture way" topics and politics in general, including geopolitics, economics, etc. They make the site actively worse on purpose on a regular basis. If you try to make any kind of good faith edit it will be pretty much immediately deleted by someone, and then you go to the history of the page and see that guy has been editing that article (and 1000 others) for a decade.<p>Of course this goes totally against everything Wikipedia originally stood for: neutrality, reliance on reliable sources, "be bold", "anyone can edit", "nobody owns an article", etc. But it doesn't matter, because for every Wikipedia policy there is another policy saying exactly the opposite thing. It's a "rule lawyer"'s paradise: if you know all the policies back-to-front, you can argue your way around any drive-by contributor's attempt to justify their changes.<p>For me, Wikipedia has gone through a bit of a cycle. For a long time, it was unreliable, but the contents were at least largely contributed in good faith. Then it seemed to get better. But these days I try to get information from any other source first, and check the citations pretty carefully. A lot of "information" is sourced from very political media outlets in the US which wear their biases on their sleeves. That's okay, those outlets should exist. But they're not reliable sources for an encyclopedia.
