I hate the arrogance and pretence of this site as a concept. I'm far more productive than pretty much anyone I know, but I also need downtime to recharge.
That said, Gagnam style brought a smile to my face and added a bounce to my step; there's room for many things in culture and not all time is wasted, even "downtime". I'm sure Bach took breaks too.
Gangnam Style is brilliant. You can watch it dozens of times, always discovering something new. It also spawned a large number of extremely entertaining spoofs.
It would indeed be a sad world if we had peaked culturally at Bach. Fortunately, we haven't.
The terms arrogance and pretense were used for a reason.
