After a few weeks of using OpenID, I’ve come to the conclusion that it is awesome.
I guess all I needed for some convincing was a few good applications to use it with. I have been using it with Ikiwiki and Movable Type, and its a breeze! MovableType even has a support for trusting OpenID users. What really makes it cool is that the authentication part of the process can be delegated to a different mechanism that the identifier.
I’m going to try adding OpenID support to PhunkyBB asap.
Thanks so much to the folks who dreamt this up - bfitz right?
