Simon Willison’s “How to Use OpenID” screencast did a lot of good — raising the awareness of OpenID and how it works for users. Today, the major bottleneck is getting more web applications to support OpenID logins.

It’s not quite as polished as Simon’s and I tripped on a few things — e.g. OpenID Identifier — but check it out and feel free to forward it on to anyone who might want a deeper picture of how OpenID does what it does.
