The centralization of online identity angers me for two reasons.
First, centralization concentrates power and we all know how that goes. It's also brittle and I really, really want the global internet to be as resilient as possible.
Second, I spent so much effort around 2007 trying to convince my telecom clients they needed to get to this first by capitalizing on the dwindling social weight of phone numbers with a transition path. But executives in both shrugged with "Facebook is just a website."
Neither my socialist nor capitalist side can win.
