Nurgled writes: On Sunday John Panzer announced that AOL now has experimental OpenID server support. This means that every AOL user now has an OpenID identifier. OpenID is a decentralized cross-site authentication system which has been growing in popularity over the last few months. AOL is the first large provider to offer OpenID services, and though they do not currently accept logins to their services with OpenID identifiers from elsewhere, they are apparently working on it. The next big challenge for OpenID proponents is teaching AOL's userbase how to make use of this new technology.
