I just recently asked a question which got "on hold" because it was unclear. So I read the related meta-posts, i.e.
I agree that my mixed language might give me a bad impression. But I feel my main problem is that the questions I ask, are outside the main interest, and thus mainly not understood correctly by the common readers. (Source of this idea is the many Revival-badges I've had.)
As an asker, it's pretty annoying to try to balance between short question and complete background question. Especially when these sources are not in English. At "too quick with the close" meta-post there is a comment from Bratschley; "An asker is by definition very likely to be unable to intelligently discuss the specific topic they're asking about" And I also agree with the choices given there by George Stocker;
Ignore the question, hoping the user magically figures out there's a problem with their question (or that for the 9K questions we get, we have enough people on hand to actually close the questions that are unclear).
Take the most time I can spare to that question to let the user know why I'm closing it, and putting the impetus on them to fix their question
Take more time, edit it for the user, hope they learn something from the experience, and maybe they'll formulate the question better next time with that magical experience of me editing their question.
Which of those actions has the greatest liklihood of spreading change throughout the userbase and effecting positive change? It's not #1, and #3 will always lose to the masses.
So my point to this Meta-question is to say that actually a lot of the questions in PSE are "unclear what you're asking"- to me. But this is obviously my own problem, and I still like to read these. And I think this character won't change even if I had 200k reputation. This site's name is "exchange", and the thing we are changing, "my unclear" to your "clear" and vice versa. It's just pretty frustrating to have a lot of dialogue to just the get the question open.
So my proposal for the solution in a form of a question is;
Should there be reputation limit, ie. "Established user" which closes out the possibility to close a question by the reason; "unclear what you're asking"?
I mean established users might be magically able to figure out there's a problem with their question against the option that they discouraged away by the continuous struggle with some minor issues in the language and/or contest. As I get such an reply's also in "real life"; "Es ist wirklich schwierig, Ihrem Gedankengang zu folgen, und das liegt nicht allein an der Sprache". Translated: "It's really difficult to follow your thoughts, and it's not only a language problem".
