Facebook, when it began, like Google, was very resistant to advertising. They knew, like all - Mark Zuckerberg, like all good engineers, knew that advertising makes the product worse. But, you know, over time, they've been forced to increase the advertising load more and more and more. And the way they advertise is they - it's subtle but they know everything, you know, about everybody on the site.

I wish more of the web had stayed nonprofit. But the advertising model took over and I think has delivered us to where we are, along with the development of content, which is designed to do nothing else but make you click on it or share it. And I think it's kind of a low goal for content, and I think that's taken us to our current abyss.

There's always going to be a tradeoff between trolling and anonymity, and I guess that's the way life will be. And you can manage it, but you can't cure it.

I think that's been really the key, the idea of trying to harness social capital for selling purposes. That we've let this happen so easily without clearly getting something in exchange is kind of amazing to me.

In fact, the big steps forward for advertising, especially after World War I were when government just began employing the tools of advertising for its own purposes to get people to join the army and other things.

I'm afraid when too many people know too much about you, it actually makes us all a lot more boring because you're afraid to express yourself.

There's always going to be merchants who need to get their message out, but things have gone way too far.
