Depends what you mean by "succeed". Commercial viability for anything remotely approaching the design intent of SO is probably impossible. But anyone can just start building a useful Q&A database and hope others stumble on it. The point is that experts, who have been through many years of trying to help beginners in the pre-LLM era, also know what questions to ask, and how to phrase them, and how to disentangle the concerns that beginners have.

Or at least they should. I think too many people get into a routine of letting themselves get angry about the repetitiveness of the questions they're answering, and then somehow getting addicted to that.
