>They are probably like me: if punctuation isn't on my keyboard, I don't use it.
LPT: on Android, pressing and holding a punctuation key on the on-screen keyboard reveals additional variations of it — like the em-dash, for example.
This is the №1 feature I expect everyone to know about (and explore!), but, alas, it doesn't appear to be the case even on Hackernews¹.
On Windows, pressing Win+. pops up an on-screen character keyboard with all the symbols one may need (including math symbols and emojis).
MacOS has a similar functionality IIRC.
And let's not forget that software like MS Word automatically correct dashes to em-dashes when appropriate — and some people may simply prefer typing text in a word processor and copy-pasting from it.
Anyway...

¹ For example, holding "1" yields the superscript version, enabling one to format footnotes properly with less effort than using references in brackets², yet few people choose to do that.
Yeah, this is what I don't understand, surely people aren't "using" em dashes deliberately. I assumed MS word was just inserting them automatically when the user used a minus symbol between two words. Kind of like angled quotes.
I'm used to simply using a single dash - and I am surprised that anyone who isn't an AI would feel strongly enough to insist upon the em dash character that they would use them deliberately. I will admit the use of a dash (really an em dash in disguise) in that previous sentence felt clunky, but I just felt I needed to illustrate. I mostly write text in text boxes where a dash or pair of dashes will not be converted to an em dash when appropriate, and I often have double dashes (--long-option-here) auto-converted to emdashes when it is inappropriate, so I really dislike the em dash and basically don't use it. Doesn't really seem to be a useful character in English.
