Nat Sakimura, tireless OpenID promoter in Japan and initiator of the OpenID Foundation’s Japan chapter, writes:
The largest Japanese SNS, Mixi, started to offer OpenID as of today.
This great news comes on the heels of the MySpace OpenID announcement. Other social networks can’t be far behind?
He quotes Mixi’s CEO who summarized OpenID advantages to them: "[OpenID] is a mechanism to extend Mixi’s social graph to the internet through OpenID."
Well said, and congratulations.
