The disconnect here is that they built it this way, but still call it a question and answer site and give a lot of power over to the person who created the question. They get to mark an answer as the solution for themselves, even if the people coming from Google have another answer as the solution.

If they were to recreate the site and frame it as a symptom and issue site, which is what the interview described, that would yield many different choices on how to navigate the site, and it would do a lot better. In particular, what happens when two different issues have the same symptom. Right now, that question is closed as a duplicate. Under a symptom and issue site, it's obvious that both should stay as distinct issues.
