Well, be ready for bitter threads populated by people whose images were rejected by the "special gallery." Your expert judges will be called elitist snobs choosing images that match their personal taste (even if far from the truth). Hell hath no fury like an artist scorned. I'd be wary of this idea if I was the decision-maker at Rendo.

As for no one saying anything about changing the current situation, I thought the thread was started (and many comments posted) in hopes of changing a system that rewards people for putting up renders that some or even many feel don't deserve praise.

I agree that automatic praise doesn't do the poster any favors in terms of his or her learning curve, and renders the rankings meaningless. So get rid of the rankings. They just encourage high-volume posting of renders and high-volume exchanges of automatic praise.
