A very interesting article and one I'll have to spend more time thinking about, but here are a few quick impressions (author's quotes italicized)
The problem, from an artistic point of view, is that photography starts with an external point—a subject—and a mechanical capture, from which it can't escape.
Yes, usually photography starts with an external subject, but the best photography is subjective as well, and more about the photographer's internal response to an external subject, to the objective reality in front of him.
if you want to go looking for a true, lasting art in photography, you should look at things that can only be captured in an instant: an action, an event, a happening.
I think the author is much closer to the mark here. While I can appreciate good landscape and still life photography, it doesn't move me like good street photography or event photography, genres that capture fleeting juxtapositions, subtle expressions, the briefest of moments when the eternal flux is exquisitely balanced on the razor's edge (okay, enough florid prose. I guess the No BS title of this thread doesn't apply to me!) - in other words Cartier-Bresson's decisive moment, which he describes much better in his famous essay than I ever could.
In this type of photo I find a curious and wonderful mixture of art and serendipity and luck - as Bill put it so well, "We deal in a moment. A painter takes a little longer. In a sense, we are the sketch artists; they are the sculptors. It gets complicated. But I think much of the best of photography is somebody saying, “I saw something wonderful. Let me show it to you.”
On the other hand, I think photos will be regarded as the most important documents of our time, and that it’s in documentation that the true Ort of Photography lies.
I agree with this up to a point. When documentary photography is done well it becomes transcendent, but just as I'm not so sure there is a distinct line between fine art and commercial art, as the author asserts, neither is the line so easily drawn between documentary photography and art.
