Dear megan and others,
I also am enjoying the way this conversation is going. Very constructive and edifying, to me at least . By way of continuing the Converstion, I just posted an article on my blog (The Window of My Lens). It deals with what a photograph says to the observer (if it says anything at all), and by exstension, what any piece of artwork says. I hope the article stimulates some discussion and thought.
