An anonymous reader writes: As rumored last week, AOL's John Panzer has now announced support for OpenID for all AOL/AIM users. He begins, "I think that user-centric, interoperable identity is hugely important to enable the social experiences we're trying to provide. This is a work in progress, but things are coming along thanks to our authentication team's diligent effort." With AOL joining Microsoft and (unofficially) Yahoo! in supporting OpenID, will Google be next?
