I like the idea of giving space for team/employee Q & A and sourcing both the Q's and A's from employees themselves, seems a no brainer for sure. Another implementation of this would be a client and employee space for Q & A where both employees and clients have the option of posting anonymous questions, and even anonymous answers.
Anonymous option because some people have both questions as well as answers but they aren't always sure enough about it to drive optioning their feedback. Whether answers given are correct or not is of no consequence. I believe inaccuracies would only increase the individual drive for involvement. So long as reviewers/users are clear on the risks involved in such a support setup and/or following suggestions blindly).
(Adobe has something like this kind of feedback system in a part of the cloud infrastructure of their XD software (could be all of their offerings but I happened upon the XD one by accident and is the only one I've seen. Enployees (who are not support) are very active in answering customer questions and difficulting as well as giving tips and walkthroughs).
