My opinion on this is that such an hypothetic forum need to display credentials (what makes you an expert) and ban people that lecture people full-time, with no credentials to back it up whatsoever. The most critical people on Internet forums are also the most anonymous and often there haven't achieved very much, if at all. They poison the water for pragmatic people, who leave first. EDIT: also, it seems to me forums that skew higher-class will prefer posturing and talk rather than work credentials.
