Its funny that people think that conventions for typewritten text built around the limitations of typewriters define what is “proper” in environments where typewriters and their limitations are not involved.
Yes, this always grinds my gears too. There is already a slightly larger space after periods in contemporary typefaces.
The old typewriter typefaces were monospaced, ie. every character was the same width, but this is no longer the case. Virtually all typefaces today are proportionally spaced, not monospaced. So it’s redundant to leave extra room after periods.
What does this have to do with what I wrote? I said nothing of the sort. In fact, I explicitly pointed out that HTML and WYSIWYG word processors address it automatically.
