I feel that your optimism is unfounded. The specific kinds of fora you say are necessary, are a dying breed. They simply aren't as available to an internet user as before the rise of walled silos. Even where a forum is available or a user has the technical skills to put up his own forum, that forum is nothing without people other than yourself congregating there, and they have mainly left forever for the walled gardens.
