In theory dividing the 2D gallery does sound like good idea, I agree with what you say about PS Grim but I'm not sure just how much difference a software specific gallery would make. You say "Using Photoshop effectively requires skill, but the rate at which these images are buried in the 2d gallery does not allow time for proper attention and critiques." I would imagine that a lot of the images in 2D are created in PS but without some criteria other than software for posting I think the images you hope to see will be buried almost as quickly as they are now. I think Scott's idea for an area in the PS backroom may be a better way to go for the attention & critiques those images deserve.
