I tried to find a faq post about that, but couldn't find one.
When should one directly edit a post and when should one just suggest improvement in comments instead?
So far, I have been using my "gut feelings" but, for people on the autism spectrum (like me), clearly stated rules are much less stressful.
I'm asking this because we had an "incident" today when someone took real offense of an edit while the all issue was only due to miscommunication.
The faq post about What is the etiquette for modifying posts? is interesting but doesn't talk about when one should be commenting instead of editing.
The faq about How do suggested edits work? don't really talk about when one should edit or not.
