In an ideal world, LLMs would take all of the basic RTFM style questions, and leave SO for the harder, but still general enough to be applicable to others-questions. LLMs seem to be getting pretty good at those as well though, so I don't know where that leaves us.
SO for discussions of taste? I have these two options to build this, how should i approach this? They tried to sell their own GPT wrapper for a while, didn't they? The use case I can see for that is: User asks question - LLM answers it - user is unsure about the answer - it gets posted as a SO thread and the rest of the userbase can nitpick or correct the LLM response.
Edit: I also seem to remember they had a job portal in the sidebar for a while, what happened to that? Seems like a reasonable revenue stream that is also useful to users.
