“The fact is that if I sign in to a free site using my Twitter login, I’m actually more valuable to advertisers than if I paid to enter that site. That’s because the list of people I follow on Twitter says a huge amount about me, and a smart media-buying organization can target ads at me which are much more narrowly focused than if all they knew about me was that I was paying to read the Times. We’re not quite there yet. But it seems to me that online publications are making a big mistake if they make subscribers go through a dedicated registration and login process, because the demographic information they can get from that will be less useful and less accurate than if they outsource the reader-identification procedure”
