Should edits that only remove a "Hi" or "thanks" be rejected as too minor?
The Edit Q&A says, "Try to make the post substantively better when you edit, not just change a single character. Tiny, trivial edits are discouraged." That doesn't directly answer my question, but IMO just removing a greeting or closing doesn't make the post substantively better. So if that's all an edit does, I usually reject it.
In Edit powers activate! Removing Hi/Thanks the consensus seems to be, yes, go ahead and edit to remove greetings and closings. But that's not the same as asking me, as a reviewer, to approve those edits. So how much discretion should I have to reject them anyway?
