I sense an opportunity to create a new kind of social identity for us to leverage around the web, one that is far more personal and instrumented than a Facebook profile or a Google cookie. It’s an identity that is independent of the one we’ve cultivated on Dependent platforms, but not necessarily separate from them. We can chose to include our Dependent Web profiles, but we don’t have to. At the moment, the model seems pretty black or white. If I’m logged into Facebook and the site I visit is using Facebook’s services, that site knows more about me than probably most of my friends do. In other words, perhaps it’s time for a Revealed Identity, as opposed to a Public or Dependent Identity. As human beings wandering this earth, we certainly have both. Why don’t we have the same online?
