Actually, I seldom use a wp, choosing instead to carefully write my post or reply, then preview it for continuity of thought and relevance.
But too often I hit "Submit" only to re-read it and find a necessary addition or deletion of a word or words in interest of clarity and less often, brevity (self-evident.) And sometimes of late, to keep me from getting banned!
I do have a code though and that's only to edit for those reasons or other grammatical error and NEVER to change or diffuse the meaning or intent of my position, whether popular or not. I set that as a strict rule before I ever made my first post anywhere.
I'm not a perfectionist but find my method to be very therapeutic and entertaining. Well, to me anyway.
I also learn a lot by trying to write correctly.
See Jo and BG, I do have some merits....
but not too many.
