I think in the era of LLMs good docs/FAQ are of an even greater value.

You can write a support bot that sends a user's question + docs/FAQ to an LLM to automatically deal with the basic questions and only involve a human in the loop once a question goes beyond what's in the docs.

Even if users don't read them of their own volition, they're still valuable. You can copy/paste responses from them, link to them, or hell just use them to remember the answer yourself later without having to confirm it or even think about it.

Run stats on support requests and make canned/auto replies for the common ones?
