Whcih is pretty bad for both developers and users, as a user I cant run my own identity provided and as a developer I have to spend time setting up accounts with ever identity provider i wish to integrate.

Original OpenID just let me as a user use a URL as my identity, so I could use any identity provider I wanted, including running one myself.

EDIT: There is a specification for dynamic client registration but nobody implements it as far as I've been able to tell.
