We've probably all seen comments in G2G from time to time by members (me included) who have been here a while and remarked that when they look back at some of their early, rookie work, they are appalled by how crappy it was. But they persevered and improved over time, their standards improved, and they developed a better style by paying attention to the work and comments of others. So the site, to a large extent, is serving as a training ground. In order for the site to be what you want, it would have to cease being a training ground and become a private club with stringent membership criteria, and it would need a staff to evaluate qualifications of prospective members. It would need to accept only professionals or those who have obtained training and experience elsewhere. I doubt that many of us who just pursue this as a hobby would bother to subject ourselves to a strenuous "initiation" rite.
