> Or rather, my right thumb does. I learned to type on an IBM Selectric, I use mostly mono-spaced fonts, and two spaces after a full stop makes perfect sense. I went thirty years between learning it and thinking about it, and then some point-and-drool twee bloggers made it unfashionable.
I actually learned to never use double-space-after-period for text that would be rendered directly (e.g., not by a typesetting toolchain that would replace it with a more appropriate but not available in ASCII wide space) in proportional fonts before the Web existed, and it seemed to be fairly widespread advice. This is absolutely not something that was originated by “point-and-drool twee bloggers”.
