The New Generation Gap?

I finally had a chance to read this essay Darren Barefoot linked to on his blog last week:

Say Everything
As younger people reveal their private lives on the Internet, the older generation looks on with alarm and misapprehension not seen since the early days of rock and roll. The future belongs to the uninhibited.
By Emily Nussbaum

It's an interesting read, and quite timely with Northern Voice almost here. Be sure to read the comments, as well. A historical perspective would also be interesting. It seems to me book publishing created a similar situation, but I'd love to see the details to prove or disprove this.
