I ran across this video today and had to pass it on. When preparing your manuscript for an editor, the serial comma is something you’ll want to keep an eye out for. Why? It’s an easy fix, first of all. Secondly, if your editor doesn’t have to stop every few sentences to deal with commacide, they’ll have more time to focus on the heartbeat of your story.
This is your mission if you choose to accept it. Watch.
