I'm finding this is happening a lot - people are editing questions and answers, not with objectively necessary improvements (fixing typos etc) but subjective amendments.
e.g. I've just got one where a sentence beginning with "One of the most important differences..." has been edited to "One difference..." Accepted that the editor thinks that the difference is actually not a very important difference; surely this type of edit alters the tone of the answer to the point where it's not the answer that the answerer originally intended to make?
I'm particularly interested in this because I've had my questions edited with "helpful clarifications" to the point where they're no longer the questions I wanted to ask! It seems very easy for people to edit stuff almost beyond the point of recognition in this way, and I was wondering if there were any guidelines to how far edits of this type should be allowed to go, or if anyone else had any strong opinions on the subject?
