The matrix article is really unusually bad. One of the problems, I think, is that there are competing "views" of linear algebra. Mathematics students are taught a different class than everyone else where vector spaces and linear functions are brought to the fore. Everyone else seems to get a more computation-focused course. So there's a tension there where if you write a math-style article about matrices where this fact about the columns would probably be the definition of a matrix, everyone else might not even recognize what's going on. There's also the issue that the current article is so sprawling that refactoring it to subject it to a unifying plan would require a large rewrite, and that's hard in an environment like Wikipedia.
