I absolutely agree...I did a piece called Dragon! last year after the Mil Dragon came out and posted it to a Live Journal community I belong to because I was proud of it. it received an anonomous comment of:

"Another poser picture wooohooo. You do know why that program is called poser. Its for Poser 3D people that can not do anything in a real program. So forgive me if I'm not too impressed, although the layout of the picture is nice and it looks good, but it would impress me if you had not used prefabricated models and textures. Now you have layout, try a real program, LightWave, Maya, 3D studio max, and build a real 3D project."
I was so angry. But I felt a bit better when the piece won honorable mention in the DAZ medevial contest :). Why do people assume that just because someone uses Poser they have no talent? If anyone's interested, you can see the image in my gallery :)
