Billions of photos are shot every year, and about the toughest thing a photographer can do is invent an original, deeply personal, instantly recognizable visual style. In the early nineties, Wolfgang Tillmans did just that, transforming himself into a new kind of artist-photographer of modern life.

Abstract Expressionism - the first American movement to have a worldwide influence - was remarkably short-lived: It heated up after World War II and was all but done for by 1960 (although visit any art school today and you'll find a would-be Willem de Kooning).

Yes, 85 percent of the art you see isn't any good. But everyone has a different opinion about which 85 percent is bad. That in turn creates fantastically unstable interplay and argument.

Many museums are drawing audiences with art that is ostensibly more entertaining than stuff that just sits and invites contemplation. Interactivity, gizmos, eating, hanging out, things that make noise - all are now the norm, often edging out much else.

I often find myself privately stewing about much British art, thinking that except for their tremendous gardens, that the English are not primarily visual artists, and are, in nearly unsurpassable ways, literary.

When people in stadiums do the Wave, it's the group-mind collective organism spontaneously organizing itself to express an emotion, pass time, and reflect the joy of seeing the rhythms of many as one, a visual rhyming or music in which everyone senses where the motion is going.

Rumors sound of galleries asking artists for upsized art and more of it. I've heard of photographers asked to print larger to increase the wall power and salability of their work. Everything winds up set to maximum in order to feed the beast.
