@kagan The only people who don't regularly use em dashes are people who use Windows, because it's the only common operating system that makes it practically impossible to type them.

(It's ALT+0151, *if* you have a full keyboard.)

And the sad thing is, Windows has been the most popular OS for over 35 years, now, so most people never learned how to properly use typography on a computer.

I suggest "The Mac is Not a Typewriter" (1995), by Robin Williams, for people who didn't get the memo.
