Wordpress.com += OpenID

Simon blogs it.  Cool!  Wordpress is a provider only for now, not a consumer.  Meaning you can't use http://journals.aol.com/screenname to leave comments on Wordpress.com blogs.  Which is fair because you can't use a Wordpress URL to leave comments on Journals yet either.  The effort to consume OpenID is higher than providing identification on top of an existing authentication system.  Hopefully soon (for both).
