Marc Canter leapt to OpenID’s defense against Michal Migurski’s criticism.

…there are those who think we DON’T need anything more than simple single sign-on. In fact I had lunch with the CEO of SixApart (Barak Berkowitz) who said Brad Fitzpatrick is fairly skeptical of anything beyond his original simple scenario.

But, says Canter, “we need the attribute exchange to make this thing really take off.”

Then all the skeptics will realize that the authentication layer HAD to come first - but was just a first step. Along the way we’ll figure out standards for user intrerface and usage flow.

But for now - the critics are right - OpenID as it stands right now is just authentication and that ain’t gonna rock nobodies world - except for Bard Fitzpatrick’s world - I guess.
