What's so interesting about the internet - I keep saying this - is the web has gotten worse over the last five years as opposed to better.

Trolling is an ancient problem. It's been around as long as there has been media.

Google - and some of the other sites, YouTube and, you know - Google has an amazing search engine. The map product is incredible. So there's a sort of exchange when you put up with a bunch of ads. Facebook basically gives you access to your friends who, in theory, you had access to already. So sometimes I don't really understand the deal, but I guess it makes it slightly easier. So that's their contribution.

Markets are born free, yet no sooner are they born than some would-be emperor is forging chains. Paradoxically, it sometimes happens that the only way to preserve freedom is through judicious controls on the exercise of private power. If we believe in liberty, it must be freedom from both private and public coercion.

Right now it is illegal for a service provider to censor or block a site because they don't like it or to privilege someone who pays them extra money. So it's basically a level playing field. I think it was a great victory. It doesn't solve all the problems of our time, but I think we've gotten a much better place.

We have just decided we have to have everything for free. And I think we're starting to pay for it in terms of our mental states.

You have to think back to the '90s. The computer was this terrible-looking thing that was trying to compete with the television. And it was this idea of email and chat rooms and this kind of stuff that first people - got people there.
