There seems to be a bit of difference of opinion here about editing questions to improve them with regard to English usage, capitalization, grammar, and punctuation.
In this meta question, @Nick posted an answer which called me out for "putting lipstick on a pig" with a link to a question I never edited. It was edited by another user to improve gross capitalization errors. It (currently) has a score of -2 (+1/-3), probably garnering down-votes from its pre-edit state. It's still not a great question, but it is more readable. The posted answer was accepted and has an upvote.
I fail to see why anyone would object to attempting to improve the question for future site visitors. Therefore, Nick's answer seems somewhat off-base. He did say:
We are still waiting from the O.P. for a schematic, or diagram, or any other clarification.
That's fine. What's stopping the OP from adding said information? It's not as though the OP is likely to fix English mistakes when adding a schematic, so why object to another user volunteering to do so?
More recently, another lack-of-effort homework question was posted with a silly misspelling and a couple of words to capitalize:
an electric cattle has coils A and B.When only A is switched on the water boils in 10 minutes and when only B is switched on water boils in 20 minutes.Calculate time taken by same amount of water boil if the coils are connected in series
I edited the question but still voted to close it. My thinking is that if the OP wants to show some effort, they can edit their question to do so, and perhaps salvage it.
@Olin posted a comment:
Please don't "fix" attitude problems in questions. The OP's disdain and disrespect for us should remain visible to all. Fixing the letters doesn't fix his attitude, which is important information in deciding how to react to the post. In short, you are depriving us of useful information by covering up for the OP. If someone is thumbing his nose at me, I want to know that before deciding whether to answer, downvote, and/or vote to close.
I'm surprised by this, because I don't detect any "attitude" in the question. As much as it sucks, I've gotten used to the fact that questions often need editing and interpretation. The site attracts a lot of non-native English speakers, which is great for an international scope, but questions will sometimes require a bit of cleanup.
In this case, the OP dumped a no-effort-shown homework question on us, which happens with annoying frequency. Still, there are some good homework questions from time to time. If the OP learns from comments and modifies the question, what is the harm in editing it?
Questions that are beyond salvaging, I won't edit. It is my hope they get downvoted and deleted, and disappear. If the homework question never gets improved, then fine, editing it was perhaps a waste of time.
The site is for Electrical Engineering. This is a field which requires clarity and precision, otherwise time-consuming mistakes start to add up. I do not view edits as cosmetic or "beautifying", but rather as making things clearer or more accurate.
The FAQ says to avoid trivial edits, and there are ancient Meta.SE discussions about whether to edit to only remove greetings and thanks. I never try to change the tone or meaning of a question, only make it readable and/or conform a bit to standards.
Voting is supposed to be about the quality/accuracy of the question or answer, not whether it conforms to language standards.
So what's the problem?
