I find Facebook absolutely fascinating because I don't think there's ever been any one source that had so much information about each of us - who we talk to, who our friends are, what books we read, what we're buying, what movies we saw, what our travel is.

Targeted ads, I think, are useful because I don't want to see all the crap. I'm not interested in buying a Mercedes Benz, but I am interested in buying a new MacBook Air. So if organizations like Facebook can actually make the ads more relevant to me, if they know what I am interested in, I have no problem with that.

Some people think that Facebook is fantastic; other people are very worried about it.
