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.

All great contemporary artists, schooled or not, are essentially self-taught and are de-skilling like crazy. I don't look for skill in art... skill has nothing to do with technical proficiency... I'm interested in people who rethink skill, who redefine or reimagine it: an engineer, say, who builds rockets from rocks.

If the Frieze Art Fair catches on, I imagine at least two great things happening. First, we will once again have a huge art fair in town that isn't too annoying to go to. More importantly, Frieze may finally show New Yorkers that we can cross our own waters for visual culture. That would change everything.

Contrary to popular opinion, things don't go stale particularly fast in the art world.

'The Panorama' is also the last place anywhere in New York where the World Trade Center still stands, whole, as it stood in the early morning of September 11. I can also see the corner where I saw the first tower fall and howled out loud. Seeing the buildings again here is uplifting, healing.

New York being what it is, our museums are vertical, not horizontal. That means the stumbling blocks to architectural clarity are unavoidable - but certainly surmountable.

I have a soft spot for art that, in terms of subject matter and material, is in bad taste.
