Things are getting hot around OpenID. First Microsoft announces that CardSpace will “interoperate” with OpenID (I only airquote because the commitment is pretty vague right now, but it seems like goodness), and now AOL has given all their screen name users an OpenID URI.
Every AOL/AIM user now has at least one OpenID URI, http://openid.aol.com/<sn>.
Where <sn> is your AOL screen name.
That’s 60MM or so newly-active OpenIDs in one fell swoop. Granted, most AOL and AIM users wouldn’t know what to do with their newly-minted OpenIDs, but it’s nice to see the infrastructure there for when the concept’s mature enough to start to take popular root.
