I think one reason why they like unrealistic shapes (Macho-man Mike, Nude Vickie in Temple with Sword) is that these shapes are rare in real life, and represent the opposite of the respective normal body types. So it's a form of escape from the real world to manipulate those atypical forms in Poser. It may also be one reason why 3D snobs and "artistes" hate Poser: they see M-M-M and NVITWS renders and say "How juvenile and unrealistic!". I like what Poser can do, and I think it would raise Poser's esteem in the eyes of 3D snobs and "artistes" if people would consider doing renders of normal body types.
