Just a quick return from the dead to point out Dare Obasanjo’s fantastic read – Learning from our Mistakes: the Failure of OpenID, AtomPub and XML on the Web. An insightful article that ring true to me through personal experience in each domain. Mind you, I still utilize all three technologies in useful scenarios every day and find them all to be elegant solutions to my specific problem domains, but I wholeheartedly agree with Dare’s conclusions.
