What do you think of when you think of editors? Do you think I spend all my time reading grammar articles? Worse yet, do you think all editing does is nitpick grammar?
Editing includes so much more than basic grammar. Editing looks at readability, accuracy, and engagement. I also spend a lot more time looking up random things for context than I do reviewing the many ways a comma can be used. My grammar game is strong, but my knowledge of the first parachute jump is not.
