I haven't followed OpenID since v2. it had potential with v1.1 and the SReg and Attribute Exchange extensions. unfortunately, they were only extensions and therefore not mandatory. when v2 was released and big players like Yahoo adopted it, everyone wanted to be an OpendID provider (=control identities)
