Actually that's fine. StackOverflow, Reddit, HN are or at least were populated by people. Looking to them for answers is doing a survey of best practices for a topic and will at least tell you what is popularly true.

Asking AI sometimes gives you the same answer as AI is trained on these same forums, but not always.

Your prompt structure and/or inference bugs (which is a lot more common in smaller providers or local hosting) can change the answer AI gives.

And ofcourse, if there's low/no data, AI will still give an answer even though it's not in the safe zone.
