NEWS FLASH: Google has no frigging idea what identity on the internet means.

“Circles is particularly well suited to the contact list you have in your phone, we have a somewhat different view of privacy. We tried to build a system that you could use for the relationships over time. The people who built the Internet did not get a stable version of identity; You need identity, in the sense that you are a person, this is who you are these are your friends and so on … The issue on the Internet is not the lack of Facebook, the issue on the Internet is the lack of identity. “
