You'll remember, I trust, that the part of this discussion where I first started disagreeing with you began with the implication that we can "get just about anything 3D-related" here.
It's my assertion that that's not true, and I could probably come up with a thousand more examples if I had to.

Renderosity began as a Poser emporium, and that's essentially what it remains, in spite of it's weak attempts to break out beyond. It's basically the Amazon of the Poserverse.
It is astonishing, though - I would think that for all the members - for all the latent potential to become something bigger, it still does its best to appeal to the wannabees with promotions like "Monet Monday" and such, which are pretentious, at best. (Not to mention the laughable Rudy Sarzo thing).
