I was reading this answer to a recent question about how to get honest, unbiased feedback on writing from friends when I noticed the author had accidentally used the wrong character to close a parenthetical statement. I was about to edit the answer when I saw this line at the top of the screen:
"We welcome all constructive edits, but please make them substantial. Avoid trivial, tiny one-letter edits unless absolutely necessary."
My edit, of course, would be a one-letter edit. How do I determine if it is "necessary" to make it? While the punctuation error is distracting, it doesn't change or confuse the author's intended meaning from what I can tell. Would this mean it's too insubstantial to make?
