If you're specifically talking about my use of "more correct", let me try another example of why I think "more correct" is useful nonsense. I'm Canadian. Therefore, I use spellings like "colour" and "honour".
However, if I'm writing something primarily targeted to Americans, I switch to honor and color. It isn't that colour becomes incorrect when I write for an American audience. To me, color is always wrong. But, if I want to influence an American audience, color will be the correct spelling they're looking for.
When I'm obsessing over edits, especially when underlying rules are unclear (or non-existent), shades of correctness are the best metric I can find. Do you have another?
