I was invited to give a talk at the OpenID Summit as a follow-up to my talk “What an RP Wants“, which I gave in February at the OpenID Design Summit. In both cases, I shared my experiences from Plaxo’s perspective as a web site that is trying to succeed at letting users sign up using accounts they already have on Google, Yahoo, and other OpenID Provider sites. This talk reviewed the progress we’ve made as a community since February, and laid out the major remaining challenges to making it a truly-successful end-to-end experience to be an OpenID Relying Party (RP). - Matthias Pfefferle
