I get that editing a question or answer is part of this site, but it seems to me some people are too quick to do so.
Further, some edits completely change the nature of the OP - and that's simply wrong.
My feeling is that just because you don't agree with how the OP phrased their question or answer doesn't actually give you the right to make an edit - even if you're a moderator.
It's absolutely okay to suggest an edit, or request it to be rewritten for clarification, but it's not okay to force an edit on someone.
I would also suggest there needs to be a time limit (say, one hour), during which no one except the OP can make an edit. This allows the OP to double check and alter things before you stomp all over it with your personal aesthetic.
Don't forget that despite the guidelines, people will write in a way that makes sense to them. That should be respected. Correcting spelling is one thing, but moving lines around or re-writing entire paragraphs is not acceptable. It's not your question/response.
That's my rant. I've written it in response to some heavy-handed editing that I've seen on some questions & answers.
What are your thoughts on this?
