In moving through the ever-increasing close queue1, it is hard to not note that many authors of questions, and occasionally answers, are simply bad at presenting in writing their question (or answer). There are some common pitfalls I see:
Extraneous context: The user includes information such as "I'm having an argument with my boss" or "I am new to this (so please be nice)", or even "I have a problem" (which ought be self-evident). This information gets in the way of the question itself, is useless to anyone trying to answer the question, and doesn't even provide ancillary or meta-benefit (if someone is rude in a comment or response, that should be handled by other systems).
Spelling and Grammar: These things do get in the way of the reader understanding the question, and it's been posited that English is an important skill for programmers. The only recourse on S.O. is for an editor to come along and clean it up, but sometimes this task is so monumental as to be unappealing. This pitfall could extend so far as to include run-on sentences, word choice and other Strunk-and-White type problems that really get in the way of understanding what is being said.
Multiple Questions: Users often ask multiple questions at once. While it's entangled in their own mind, these questions are really separate things.
Terrible Titles: The title doesn't actually refer to the problem in any meaningful way, or includes extraneous data (ie, those things that should be in tags and not titles such as language).
I'm sure there are others, but as these demonstrate there can be significant problems with a question that don't prevent it from being a 'good' question, as defined by needing to be closed (ie, too broad, no actual question, opinion-based, etc.). Yet it seems to me that pointing these problems out in comments is equally as bad: it clutters the discussion with meta-review. Thus; is there a way a feature could be implemented that lets a reader indicate in a dispassionate and non-personal way that the author could improve the asking of the question in certain key ways (which might need to be a broader discussion)? This feature need not be broadly surfaced; really only to the reader and the author.
(The usual caveat of apologies if this has already been asked; I searched but could not find something addressing this issue of meta-problems. Is there a better title?)
