Like, obviously around here you don’t subscribe to a subreddit, were not on reddit.
What about referring to the Original Poster as OP?
What about etiquette like marking edited posts and comments with “Edit: added words or explanations of edits made”?
Marking edits has to stay for the sake of sanity. It looks to me like a little pencil appears next to the minutes ago when a comment has been edited, but sneak edits can throw off a whole thread of replies.
