TL;DR: let's make a catalog of "How to salvage your question" examples.
There are a handful of reasons that a lot of our questions on our main site, ELL, get closed on. Except for "duplicate of ...", most, if not all, of the questions that got closes on these reasons are salvageable, in my humble opinion; be it "basic question", "proofreading question", "need more details question", "unclear what you're asking", "too broad", "primarily opinion-based", or any other reason.
Although we have links such as How do I ask a good question, and Please, everyone… details. Please, it happens time after time, and again, and then some, that we still have to keep telling our users how to ask, to add the context, to add more information, to add why it was a problem for them, to add what it is that they want to say, and so on.
How about instead of just telling our users so, let's show them?
How about we grow a thread, together, in a similar manner to our Resources for learning English or our canonical posts on the main site?
We could either modify this post and grow it into such a thread, or make a new meta post for this specific purpose. Whatever choice we pick, I'd like to propose that we have one such thread--a thread that shows how we can salvage our questions.
The best format, in my opinion, is in the BEFORE-AFTER style, that is, for each salvation, we show how the BEFORE and the AFTER look like, side-by-side (or one-over-the-other). We show the two versions, and we write a little about the weakness in the BEFORE version, and the remedies we used in the AFTER version, and we link to real questions on the main site.
We can do it right away, without any real structure. I believe that we will be able to spot the patterns after a while, and then we will group similar salvaged examples together (which are not necessarily grouped the same way as our vote-to-close reasons). Soon, we all will benefit from this effort by just pointing our users to these examples instead of telling them the same thing, over and over again.
Good idea? What do you think?
