If we generally like the way things are now, we must also ask whether our current situation is really so different from the open ages of radio, film, or the telephone. Might it not also have seemed in those times that the orgy of limitless entrepreneurism would never end? The point is that we are near the high end of a pendulum arc that, so far, has aways begun to swing in the opposite direction -toward greater integration and centralization- with a force that can seem inexorable.

Let's say you're someone's phone, and you notice that your owner is drinking coffee at certain times of the day, just very subtly indicating where the local coffee shop is which happens to have paid, you know, whoever makes your phone at the right moment. I think we're in a future where frankly we are possibly facing little tiny bits of manipulation in all of our waking hours, if we don't have that already.

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.

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.

Google's AdWords, they allow you to bid on words that people will type into the search engine, and they cost more or less. For example, I think mortgage refinancing can cost - now, it's probably hundreds, maybe thousands of dollars. So, in other words, they are allowing you to bid on what people are going to type, and that is the AdWords program. So you own certain terms, and then your ads show up as opposed to someone else's.

There is this inherent human instinct that the usual way you control trolling is you force people to use their real identities. So there's less trolling on Facebook, for example.

In the media, traditional media like print, we had boundaries. You know, we had spaces that ads didn't leave. They stayed where they were on the page. They didn't float around over the text. And we're kind of lost on the internet. We don't have any barriers. We have a demand for growth that is insistent.
