From time to time, I see a lot of editing being done that can be described as "merely a linguistic style choice", rather than a correction to spelling or a clarification of the question at hand. Often, these edits are made to years-old threads, asked and answered; and so the edits achieve little except bringing the posts back to the top of the lists.
I have had edits made to my posts (which I rolled back) that were essentially just alterations to the way I'd written something, rather than an amelioration of the content. I'd hope I don't presume too much in suggesting that my English usage does not normally require much assistance.
I'm not talking about formatting, which is of some value.
Is such a practice desirable? To my mind, if every question and answer sounds as though it has come from the same author, then something has been lost from the community.
