The very first heading in this doc was a giveaway even after your de LLM process 'The Em-Dash Pivot: "Not X—but Y"'. This title is so much AI like. I think it's the "The" in title which is putting me off and coming off as assigning unnecessary importance which is mentioned in the wiki.
That's definitely a pattern which I've seen in some LLM output, especially when users let a LLM "run away" with an idea and write a lot of text without supervision. The drive to coin names for things feels almost characteristic of self-help or lifestyle advice writing.
