Everybody talking down here is only talking about politics but for real im glad an online encyclopedia exists at all, otherwise people would have to rely on those horrible school notes websites for anything ew

Yeah, it's straight up invaluable to my work as a mathematician. Sure, you can find all the info elsewhere and the Wikipedia articles are sometimes bad or just very poorly laid out, but if I need to quickly look up what the metric is in the Poincare model of hyperbolic geometry or something, Wikipedia is where I go.

anything opinion based wiki is going to be biased, even with history wikipedia has bias which isn't very fair
