Steve has a slant about anonymity that seems to be in line with where tech is going: Transparency. Robert Scoble said the same a while back about opening all his stuff up. Connecting the dots as it were.
I started an experiment a while back slowly and quietly linking all my past online trails to a central spot. A spot that is googleable. I think I posted on here about something like that.
For me personally, the idea of transparency has been INCREDIBLY freeing. It has been my experience that most of my hidden secrets that involve interaction eventual come out anyway. I prefer to be the one that outs them. In fact, it is a large source of power.
It also has uncovered fears, insecurities, and mirror time with my personal reality. It has been a 10 year journey starting with thinking about it then with taking heavy action in the last 3 years (I believe that is right).
This, seems to me, to be not the same as privacy which I find people crossing wires on.
