The primary guide to follow is:
- Only ever edit to improve
Should I edit even though the edit makes it more close-able
"More close-able" is not "improve", it's "worsen". So no I don't think we should be editing if it makes it more closable as this is the opposite of what we want.
Either improve it so it's not closable, or if that's not possible or requires OP's input then close it - then OP can edit to fix the issue and have it re-opened if possible.
Touching on your example:
- A user asks a question
- Another user asks for clarity in the comments
- The author responds in the comments
You can edit and take the OP's comments and put them in the question (copy/paste or more likely some re-working), but only if it "improves" it. If the question is unsalvageable for some reason and the edit doesn't fix this then it should be closed, if the edit fixes it then edit ("improve").
It's better to get the OP to edit, as it gets them into the habit of editing (not always of course) but if they're not going to then I'd still edit to add data from their comment if it makes the question more viable. It's not just about the OP, as others will come and read it and try to answer etc.
It really is all about "improve" and "fix", although there are times when the scenarios cross paths:
- Don't edit if the post is terrible and needs to be deleted/closed
and your edit will not fix it (even if the edit improves it, it's
pointless)
- Edit if the question is a dupe, as it should stay as a signpost and
so good quality is still desirable
- Try to avoid trivial edits, unless a substantial fix, such as a
single rogue character out of a code block, or a typo is not obvious
and could cause confusion, etc
- Use judgement, as "most" of the time each scenario is unique, even
if only slightly
I went ahead and made the edit and was challenged for making the
question "worse". Should I have made the edit?
The question is on hold for "opinion-based". If this is because of the general scope of the question and cannot be "fixed" then I wouldn't have bothered with the edit, especially as your edit did not fix this.
If the edit improves it and the OP could edit and make it not "opinion-based", then perhaps the edit is worthwhile.
Often posts become better from a collection of edits from different users, so your edit = improvement + the OPs edit = no longer opinion-based, = a good question all round.
