This has caused a jittery split. The art scene is infested with water skimmers who flit from thing to thing and those who have never seen a show they didn't like. People mistake hipness for newness, though hip measures things by us, in, and young and is more about now than it is about new. Of course there's a load of mediocre art out there. There always is.
Mediocrity makes up most of every period.
Gone are the days of dominance, clear-cut divisions, and white guys with big guns. In today's bigger, more diverse art world, unambiguous separations don't exist. Art isn't threatening, or something you cross the street to avoid. It's big business, a tourist attraction. In London, it's front-page news.
