Broken promises. I presume you understand that some people know more about a subject than others. Barbera and some others on this site have worked very closely with the governing body in the past. Will they be better informed than someone who just reads about it? Of course they will.
In any facet of life, there are ones who know the subject better than the ordinary man in the street. So nothing whatsoever to do with a heirarchy, just common sense to pay attention to someone who has a lot more experience on the subject than us. (been there got the teashirt!)
