I admire some users that ask a very general question but get excellent answers. Such as this question: What is meant by a “random variable”? I am talking about the long answer for this question by @whuber.
I personally think this is not a good question, because too general. If I am asking it, probability will be close by too broad or get some answer like go to read a book.
But why such question exist and can get good answers? How can I do that? I am assuming this is not repeatable because it is randomly selected by some high reputation users?
