When I used to edit the submissions of my publication's regular contributors, I would always ask those who stubbornly clung to their double spacing mindset to stop doing it. Not only did I find the exaggerated gaps distracting, but as I explained to them, all text is stripped of formatting by the time it reaches the art director's computer. Their job was to provide copy, not to dress it up, which too often was the equivalent of putting lipstick on a pig anyway.

​When I use a typewriter it is to generate draft copy, which in turn is edited, and eventually converted into digital files, so anything more than single spacing is for me just wasted taps of the space bar.

Point taken. I, as so often the case, when making a sweeping generalization was mainly reliving a particular conversation with an ex when I was criticized for inserting extra space. At the time I was doing it without thinking about it based on some ancient training in a forgotten setting.

Wait... by generalizing this to "as so often the case", am I making sweeping META-generalizations...!?

Straight is the gate.
