The viewer

On an artist message board a while back, someone asked if we consider the eventual viewer when we are creating our art. A number of artists responded to the question. They all basically said variations of, "I make art for me and me alone. Screw the stupid viewers." I was the only responder who said he thought about the viewer when creating art. I mentioned how I constantly think about what the viewer is going to think, what the painting will remind him of, if he will understand what I am trying to communicate, etc.
I'm not sure if my being so concerned with the viewer is "good" or "bad".
