I think it would be useful to start a series of posts on the weaknesses of Mathematics SE for diagnosis precedes remedy.
In my humble opinion, one major weakness of Mathematics SE is that many users — including many high-reputation ones — simply do not quite know where some difficulties lie. I have worked with former mathematicians in industry and talking to them about mathematics is almost gauche, as once a real-world (non-mathematical) problem has been translated to a mathematical problem, with much exaggeration, it is either trivial or intractable. The difficulties lie in acquiring the domain knowledge required to translate the real-world problem to a mathematical problem in an artful and tasteful manner.
On Mathematics SE, one sometimes reads potentially interesting embryonic questions written by people without much mathematical training, say, on some problem from biology or engineering. If I perceive that the OP is asking the question in good faith, I often try to push the OP towards improvement of the question by asking several questions in the comment section and then editing the question in order to improve it via incorporation of the information provided by the OP in the comment section. Unfortunately, these questions are often closed — say, due to lack of clarity — before the seedling question has sprouted into a budding question that is ready to bloom. Why? An entire class of questions is being "uprooted" before one even has a chance to assess whether it's a flower or a weed. Why not be a bit more patient?
