I hope this works out, but I would have much prefered to see this done with an already existing system such as Reddit (which is the basis for this site), Discourse or Groups.io.

If a forum was created, I think it would be desireable for the content not to be Googleable. That way people wouldn't come to the site directly, only through less wrong or word of mouth. This could still lead to the degradation of the site, but it would at least buy it time to develop its own culture.
