The dashes-and-commas thread got me thinking of this, and it's only been on my mind for about 30 years. With onscreen variable-character-width fonts and word processors that do so many fancy things, this may be less important than it used to be. I think this mainly or almost exclusively applies to manuscripts (and other text in monospaced fonts), text types on actual typewriters, and plain "ASCII text" files. Is this mentioned or discussed in any style manual? I've browsed through a few and don't recall seeing it.
How many spaces do you put after a comma, one or two?
How many spaces do you put after a period (or other sentence-ending punctuation), one or two?
Is there somewhere where you would use three or more spaces?
I recall "learning" about spaces in college. Programming languages didn't care except that the literally repeated what was within quotemarks, so most people didn't add any more spaces in their programs than necessary. But I was also on one of the earlier computer discussion "forums" and noticed that some people in their written text actually added a space after their commas. How totally uneeded, I thought, but I did notice it tended to increase readability over not doing so. But then that meant I was going to have to type a space after every comma...
