@OldPalHappy Your ideas seem good in general, but I have no idea how they should be implemented. I definitely want to see the ability to moderate answers. To start with, it would be nice to remove spam and non-answers.
As for more specific explanations and more specific options for moderation, also want that. How exactly to arrange that, though... That's going to be a lot of work.
In short, good idea, but still needs work.
