My complaint about mathematics (and similar) articles is that they seem to be written for technical correctness, but not for instructional purposes. So people who already understand the concepts can nod and agree "I find nothing (further) wrong with that," while learners definitely fall down a rabbit hole of successive links. At times it seems more like lawyering than teaching. I've considered the argument that Wikipedia isn't meant for that purpose, that it's simply a repository for formulas and such, but I don't believe that agrees with any idea of human advancement and learning, and the site's own mission statement reads "to collect and develop educational content."
