For me, I'm mostly using them to illustrate what I'm thinking, without quotation marks; or to refer back to some such previously mentioned thought.

Or to not use a comma, to cram two incomplete sentences together whatever #FUamBOT =P

When people start pointing out spelling/formatting (in comments, no less...)... I'll typically just keep participating in discussions, elsewhere.

I recently purchased a GPU capable of running 16GB models (5070Ti), so definitely understand how easy it is to be susceptible to bot/AI comments. This stuff is really powerful/convincing. It replaced a decade-old machine, and runs Ollama/Qwen/Mistral insanely responsively.

But I'm still commenting pure humanly written. My PObox is listed in my profile, and I'll hand-write anybody back a similarly-efforted response card.
