I'm curious about this, another comment in the thread expressed the same opinion about math pages on wiki, while I've always heard the opposite opinion among mathematicians. Could you say a bit more on what makes pretty much all of the math pages on wiki very poorly written?

They're generally written in a way where it's not helpful to teach yourself about the topic, but is helpful to refresh yourself if you've previously learned about it elsewhere.
