It is so irritating that people now think you've used an LLM just because you use nice typography. I've been using en dashes a ton (and em dashes sporadically) since long before ChatGPT came around. My writing style belonged to me first—why should I have to change?

If you have the Compose key [1] enabled on your computer, the keyboard sequence is pretty easy: `Compose - - -` (and for en dash, it's `Compose - - .`). Those two are probably my most-used Compose combos.

The thing with em-dashes is not the em-dash itself. I use em-dashes, because when I started to blog, I was curious about improving my English writing skills (English is not my native language, and although I have learned English in school, most of my English is coming from playing RPGs and watching movies in English).

According to what I know, the correct way to use em-dash is to not surround it by spaces, so words look connected like--this. And indeed, when I started to use em-dashes in my blog(s), that's how I did it. But I found it rather ugly, so I started to put spaces around it. And there were periods where I stopped using em-dash all together.

I guess what I'm trying to say is that unless you write as a profession, most people are inconsistent. Sometimes, I use em-dashes. Sometimes I don't. In some cases I capitalize my words where needed, and sometimes not, depending on how in a hurry I am, or whether I type from a phone (which does a lot of heaving lifting for me).

If you see someone who consistently uses the "proper" grammar in every single post on the internet, it might be a sign that they use AI.

I would add that a lot of us who were born or grew up in the UK are quite comfortable saying stuff like "you're right, but...", or even "I agree with you, but...". The British politeness thing, presumably.

Just my two cents: We use em-dashes in our bookstore newsletter. It's more visually appealing than than semi-colons and more versatile as it can be used to block off both ends of a clause. I even use en-dashes between numbers in a range though, so I may be an outlier.

Em-dashes may be hard to type on a laptop, but they're extremely easy to type on iOS—you just hold down the "-" key, as with many other special characters—so I use them fairly frequently when typing on that platform.

Also, I've seen people edit, one-by-one, each m-dash. And then they copy-paste the entire LLM output, thinking it looks less AI-like or something.

As a brit I'd say we tend to use "en-dashes", slightly shorter versions - so more similar to a hyphen and so often typed like that - with spaces either side.

I never saw em-dashes—the longer version with no space—outside of published books and now AI.

Well the dialogue there involves two or more people, when commenting, why would you use that.. Even if you have collaborators, you wouldn't very likely be discussing stuff through code comments..

I'm pretty sure the OP is talking about this thread. I have it top of mind because I participated and was extremely frustrated about, not just the AI slop, but how much the author claimed not to use AI when they obviously used it.

It was not just the em dashes and the "absolutely right!" It was everything together, including the robotic clarifying question at the end of their comments.

You’re absolutely right—lots of very smart people use em dashes. Thank you for correcting me on that!
