#67 is really funny. I make it a point never to stand still at concerts where people are supposed to be dancing, and gleefully revel in the glares and eye rolls that I receive. I am also a firm believer in the philosophy that head bobbing doesn't count as movement.
This phenomena does seem to dissipate more and more as you move further away from the east coast and west coasts. I feel like the most dancing happens in the middle of America.
Other than that, the blog was funny, but I don't think that it accurately speaks for all white people. It's more: "stuff white upper class liberal people and their white hipster children love".
