Art is long

This post has been gradually accumulating over nearly two weeks, now. It began in reaction to a television programme, Who's Afraid of Conceptual Art?, which we stumbled into while looking more or less at random for an hour of diverting television. But it seems to have turned into a hybrid, partly the sort of response - I won't flatter it by calling it a review - that says well, if I'd been in charge, it would go like this... and partly just a place to stash some of the links I gathered together while thinking about that.

( Cut for length and ramblings. But it might be worth it for the links. )
