That has to do with the crowd you ran into. Burning Man is many things, but among those, it does have a lot of art. Did you go to SF Museum of Modern Art? or any of the art anything's? Same with sports. There are a ton of nerds that call it sportsball and think they're clever, but at the same time, the Superbowl is this weekend and there's a lot of sport-related things happening around the Bay Area that you wouldn't know about if you didn't look for it. So I'd be wary of drawing conclusions from such a limited sample set.
