On the Facebook side, I think it's a bit of an evolution, in that that company, which has clearly done amazing things, was, I believe, as an outsider looking in, was founded on a culture that was obsessive about the users. And they built a service that is very valuable for users, and that is to be applauded.

My father was an electrical engineer who worked at Westinghouse in Pittsburgh. When I was growing up, my mother wrote humor columns for the local paper. She was the Erma Bombeck of Murrysville, Pa.

If you take a look at the way the premium content is monetized, there's a lot of different models out there. Sometimes you pay for an individual episode, for example on iTunes. Other times you pay for a subscription. And other times it's free ad-supported.

Cultures are not very easy to change. They're sometimes almost impossible to change.
