Naturally, seeing more and more of them, and when I have one to post I'm a little unsure of the best place to put them as I don't want to spam communities with semi-off-topic posts.

We're going to be seeing more and more of these, it's just par for the course. I also know that some users are not fond of AI and might prefer not seeing those posts at all, so maybe it would be best to place them in a separate community like

/c/AI

or

/c/chatgpt

What do you think?
