I disagree—LLMs don't use them properly. They always put a space between the words before – and after – the dashed part.

Using spaces is not wrong. Typographically, a hair space or another thinner than usual space is usually used, but in plain text a space is often preferred. Style guides vary of opinion on this, but newspapers often space them. Without a space they end up looking like elongated hyphens joining the words on both sides. That's not their function.

Its not wrong for en-dashes (and en-dash set open—with space on either side—is generally an alternative to an em-dash set closed.) And its not wrong on the trailing side of an em-dash used in dialogue to show an abrupt stop mid-sentence if the stop is followed by a new sentence. And there's a few other particular uses, but, generally, setting an em-dash open is wrong.

> but newspapers often space them.

I've never seen a newspaper set em-dashes open, but I have seen them use en-dashes set open instead of using em-dashes at all. Given the space premium in print newspapers, em-dashes set open, which would consume enormous horizontal space, would, other concerns aside, be an odd choice.

This is US vs British English. You will struggle to find an em dash in any British publication.

My comment was about spaces specifically. The Guardian and the BBC use en-dashes instead of em-dashes, but both do so with spaces.

Somewhat off topic, however, I'm thoroughly convinced that there is a very high probability something is AI generated when I see Em dashes. Anyone else noticing this? ChatGPT for example almost always uses them. I'm sure they are more common in academic writing, but its now super common on boards like Reddit.

It’s largely the Baader-Meinhof phenomenon. You’ve started noticing it because you just learned about it.

I feel this is an broad oversimplification.

When looking at the context of a given text, use of certain words or punctuation, can very well indicate AI use.

The "original" example was delve. There is no doubt that AI (did, or still does) use this word at a significantly higher frequency than the average person. I would say the same about em dashes.

When browsing a Reddit thread about a video game, if you encounter numerous comments written perfectly, especially those containing indicators like em dashes, the word delve, or similar language, it certainly can raise the question: am I genuinely seeing comments from users who write this way in this specific context, or is this content more likely produced by an LLM?

AFAIK most computer keyboards don't have em dashes. Rather than hit ALT+0151 every time, I've always just strung along two hyphens, like: -- Absolutely proper and correct use of em dashes, en dashes, and hyphens is, to me, the most obvious tell of the LLM writer. In fact, I think that you can use it to date internet writing in general. For it seems to me that real em dashes were uncommon pre-2022.

As a diligent user of ALT+0151 for many years on Windoes systems, I can contradict that it is a sign of LLM writing — perhaps in combination with other factors it can be used to increase the likelihood of LLM authorship, but alone, nope.

What i've been using: Install https://github.com/samhocevar/wincompose and you can then press AltGr then three hyphens to insert one. or if you're on Linux just search for "compose key".

I've been Googling "em dash" and copypasting from the Google results for a solid 15 years now. Long before LLMs.

I modify the keymap to use AltGr+dash as em dash. Very easy in Linux with xmodmap, bit more complicated in Windows with the Keyboard Layout Creator.

Throwing my hat in here. The sub millimeter difference in the length of a dash conveys no additional meaning or clarity. It is impossible to argue me out of this position. It's not like you can reliably write these consistently by hand either without going over the top in length to make it extremely obvious.

Length of breath/pause with a longer dash. Read some -- Emily Dickinson poems – you'll find a world ––– of meaning ––– in the millimeter.

I have read her in the past and can't say there were world's of meaning between -'s. Can you link an example? I looked again and couldn't see any obvious ones. Generally she just completely abused the -. Does she even use a comma once? lol

Most word processing applications auto-substitute EM dashes as appropriate - some do it for two consecutive hyphens, iirc. I don't know if they substitute EN dashes automatically ... I don't know if there's a logic for that without understanding the text.

Someone should parse HN api and figure out total dash usage and see if there is a spike in recent times aha

I write poems a fair bit and use em dash a lot. (maybe too much and incorrectly)
