as re; the subject of poser content being scorned. i am probably one of the more vocal of your "3d elite poser snobs". but i would not choose to judge any of the poser stuff. i dont use it, thus i dont know it, so i wouldn't be interested in moderating it. there are enough experienced poser users here to ensure that the poser content gets a fair moderation. and i am sure that poser users would leave my real-time assets alone for the same reason.
although i have no love of poser, i have neither voted or commented on poser content, positivly or negativly.
the whole problem with asset creators being overly precious over their work is one that people will just have to get over. ultimately, once you put your work out to the public, you do allow others to have an oppinion on it. you cant put your work out and then say, "you cant have a negative opinion on it". decency and rational fairness is needed, by both moderators and users.
as re; the two tier system. its an interesting idea. i agree that it may promote a segragatory attitude among users. this would be a bad thing. but it has a lot of good aspects too it too.
