Don't lose sight of one of the dreams of the early Internet: How do we most effectively make a marketplace for knowledge problems and solutions that connects human knowledge needs with AI and human responses?

It should be possible for me to put a question out there (not on any specific forum/site specific to the question), and have AI resource answer it and then have interested people weigh in from anywhere if the AI answer is unsatisfactory. Stackoverflow was the best we could do at the time, but now more general approach is possible.
