First, the reason LLMs learned to like em dashes is that they are common in the training corpus - they are a thing before LLMs that LLMs have learned, not invented?
Second, work browser has nice blue swiggles under everything I write into a textbox. I dutifully click through them and accept the rephrasing suggestions. I get a lot of em dashes. My blog posts and whitepapers and stuff are full of them and other “AI tells” - but I think they read better because of it.
The blog is about AI. So yeah the TLD is .ai
I count 51 em-dashes on the page, which is extreme. They're also used in places where they don't really belong. It's very obviously LLM-generated, at least in part.
That said, it puzzles me why people don't prompt LLMs to change up the writing style a bit and remove some of the tells.
Do you really think this singular author is writing multiple excessively-long blog posts about AI per day? There are ~650 of these posts over the past 18 months. And over on LinkedIn, the author describes himself as a "Specialist in Digital Marketing, Videography / Video Editing, Search Engine Optimization, Social Media, and B2B Sales."
YMMV but this post and entire site absolutely screams "slop" to me.
