Great article! And a great addition on your part, Dave.
I’m at the end of my professional career and I am thankful to all the teachers throughout my academic preparation and beyond for the ways they helped me. On my master’s level, I had a professor who simply made punctuation, spelling and grammar changes in red ink to which I paid close attention. He wouldn’t comment on those but simply left the red marks speak for themselves. If he made comments within the genre, he explained them on the margins ("you might say this more simply like this” , kind of thing). As far as I remember, he never graded me on any of those, but on the content alone. He’s in his early 80s now and by now has written more than 50 books, so I paid close attention.
I also never attempted to write in an academic register for what that’s worth. Always thought that a bit pretentious.
A final learning was my first article written for a popular journal in my field and the editor there did a marvelous job of editing and then sending it back to me for my approval (by snail mail I’m sure). I learned the fine art of the semi-colon from him.
I think that my first papers (before personal computers) must have been difficult reading and grading. Hard work on their part, I think. I should remember to be thankful for those college teachers and now professional editors like lh here for their patience.
