For some research I looked up some very old Reddit threads a couple of days ago.

And, Oh my god, you can actually see how this style of writing influenced AI writing today, I constantly had to remind myself: "this was posted before ChatGPT released".

The reddit influence is especially true for "storytelling" writing.

I experienced the same lately. Even dug some of my old posts where I put in the effort and formatted them using reddit's markdown. Wouldn't dare it today
