I think this guy is a poor sociologist. Wouldn't study by dispassionate scholars be of more value than the blond-bewigged circle jerk he's proposing?
I will say I agree with Gaga as a useful case study of the sociological phenomenon of fame in postmodern culture... we've had some heated discussions on what Gaga really means over in off-topic, and I even wrote a term paper on her. (I am not a fan.) There's a lot to learn from her, but most of it isn't really pretty.
