On average a communication has more readers than writers, so it is better for writer(s) to use effort in order to save effort on the behalf of the reader(s).

This was especially true in the days of mailing lists and me having to beat TOFU users about the head with a clue-by-4. But, it remains true today. The median communication might be 1 to 1, but it’s much more frequent for additional readers to be added that additional writers, so maximum effort with writing is still true.

But, man, it is annoys the heck out of me when I compose informative, contexual email/SMS with several open-ended questions and get back: “yes”.
