When I close questions, I often write a comment along the lines of
This is off topic [...]. But you can ask on our Meta to get feedback and get advice on how to fix your question for reopening.
Well, I just made up the wording, but the meaning is the same. I was thinking: why not make this automatic?
- It encourages Meta participation;
- It doesn't burden anyone if added;
- Users are encouraged to analyze the issue instead of complaining about the closure in the comments;
- It encourages Meta participation (I think this is the best reason).
Now, you could say this could be done via pro-forma comment. But making it a network-wide feature, we make sure that it's something that is always there, while moderators might act differently individually.
Perhaps it could be added to the close-reason (even if I think a more visible place would be better) or as a notice. I honestly haven't figured this out yet. A possible wording:
If you disagree with the closure, please ask a question on Meta, avoiding ranting and personal attacks, but instead constructively explaining why you think this question deserves to be reopened. The community will help you fix your question, if possible, so that it meets our guidelines.
A link to the question from the comments would be useful too, but I don't know if it'd be (technically) possible to add it automatically, so that users can see the question, even if they don't usually go to Meta (again, Meta participation).
This idea is still in an early stage, I might have missed some points and I invite you to report them, but child Metas are really not so populated and this would make the whole thing easier for mods and other users.
