I'm partway through the mainstream published version of There Is No Antimemetics Division by qntm. The original was one of my favorite reads from 2024 bingo, so this kinda-reread is really comfy. I can't say I've noticed any big changes, outside of removing all mentions of SCP and reordering some chapters, but I also don't usually remember stuff in detail, so it's hard to say. I did flip back and forth between the two versions briefly at the start, and the part I was reading had definitely been rewritten, but it seemed to be mostly superficial differences rather than content.

(If your interest has been piqued by seeing other people in here read it, the original is still available here for free; just read the qntm-authored stories in order, including all of Five Five Five Five Five.)
