Just watched the video of Chris Brogan, and I think he perhaps misses the plot to an extent. We’re seeing rapid development in the OpenID space, and JanRain’s RPX solution (http://rpxnow.com) leverages many of the technologies of the Open Stack to allow users to authenticate with enabled sites using an existing Facebook, MySpace, Google, Yahoo, AOL, Windows Live or Twitter account. RPX puts the user in control, allowing them to decide how much profile information they’d like to share with relying party sites.

RPX also allows users and sites to connect across the social graph, with social publishing features that allow a user to syndicate status or activity from a site back to his/her Facebook stream.

The OpenID user experience has seen tremendous improvement in the last year, and the protocol is seeing increased adoption on the web, particularly among member-based sites and entertainment content providers, whose member base isn’t necessarily comprised of techies.
