Interesting read and thanks for the site link. Conservatism - couldn't agree more. Nostalgia - absolutely. The two extremes as a result of a universal lack of ideas - nobody doubts that. You could say exactly the same about popular music. The stasis in the arts in general is, I think, a direct result of social and cultural stagnation. This is where ideas come from and this is where we should be looking, not specifically within the medium itself. Photography requires first looking outward, then inward. Unfortunately, my reaction to what's going on within and without the arts has been to look inward - dissociation.
