In reply to the question "help pls fast need help with C++ Code [closed]", I answered in a comment, while the question was being closed:
I sympathise ESR's guide but it's IMO too long for this pupose (and from another age, or for another forum: a forum that's more explicitly for experts and perhaps less tolerant/polite). I find it so long that to suggest it to someone seems to me officious (as if I were telling them that I expect them to jump through a dozen hoops and to write a long-winded essay of a question).
Jon's blog post is, begging his pardon, quite long too. I can imagine someone looking at it and thinking "TL;DR" (especially if reading English is a chore).
What's the best thing to suggest to someone about how to to write a question? Is there a FAQ entry for this topic? Preferably, perhaps, shorter than either of the above?
The FAQ itself describes/defines what's on-topic and off-topic in a couple of sentences each; but it isn't a tutorial/explanation of what's a good (well-asked) question.
I've read the list of 'faq' and 'faq-proposed' headings and this seems to be a new one. "How do I write a good answer to a question?" already exists. There's a How to ask a smart question? which ought to be relevent but which has no accepted answer or summary.
