I saw this notice under some one-liner answer that was straight to point:
We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.
Me as an asker, I am not looking for long answers! I am looking for effective solution to my problem. On the contrary. I got several long answers that I will never have time nor motivation to read (and, more importantly, understand, since these long answers tend sometimes to be complicated, especially at STATS.SE). Many times, short and simple few-liner was what helped me most!
Please, if nothing else, at least reformulate this notice.
