Great in theory DigitalShinobi, but Renderosity is not just about the quality of an image. It is about friendships, thats what makes it a community. Yes there are many images with disproportionate numbers of comments, but they have taken the time to build up friendships and taken the time to make comments to earn that friendship, even if the image is not very "good".
Is "true" friendship really about telling your friend they suck at art? Not sure about that.
