I never let an LLM write or rewrite a post, or even a paragraph, for me. I want to write it myself and I want it to be in MY voice. I think I'm a pretty good writer and I like my writing. However, I suspect those who may be less confident in their writing use an LLM to "check" their rough draft but then succumb to the temptation of just pasting the LLM's output because it "sounds better", it's already finished and... writing is hard. This is always a mistake and no one should do it in a forum like HN. It's rude and we'd much rather hear your words and ideas as you express them.
The sad part is this ends up in an all or nothing between "Never use an LLM when writing a post" and "Have LLMs write posts for you."
