The moment you become reliant on post processing to make your photos interesting is when you've crossed the line out of photography. I'm still very, very guilty of this.
I think there is a line between post processing a raw file to edit some stuff, levels, curves and make it look nice.. to the ones that they just take an image and the photoshop everything and their momma out and in of it.. but whatever floats anyone's boat is their photos so more power to them.
