I agree with what you are saying. If we keep doing the same thing expecting a different result then we won't get it. However, if we do something different, it is more likely to give a different result. Different level of authonomites???? That will bring constructive bullying. More institutionalised bullying.
In keeping with the inspire and mentor theme of Harper Collins recent blog, how about instead of TSR, there are different levels of authonomites. 'Newbies' who need to constructively crit a few other books before they attain to the next level. 'Apprentices' who are working hard at areas of writing. 'Mentors' for people who are published or have a lot to give the other site members, e.g. people like Becca who are excellent at editing and wouldn't mind mentoring other less experienced writers.
In order to reach a higher level or keep within their own level, authonomites have to do a certain amount of critiquing each week. Not only would this keep authonomites busy, but it would focus attention back on writing and improving. If members 'play up' in the forums they get relegated to a lower level or a probationary level. People would soon learn to ignore these people who had no status.
Just my thoughts on this.
