"It would seem, despite the best efforts of those who conceived of it, that we've ended up in just the very situation OpenID was designed to prevent — scattered identities that should be, but aren't, linked to each other in any real way.
But in some ways when OpenID first got off the ground it was a solution without a problem. Now that the problem has arrived, will OpenID offer a way out? Given a scenario where you are forced to choose an identity (where we are now) and where you can define your own identity however you like (which OpenID could possibly offer), not needing to choose is almost certainly the winning idea."
