Gordon Cook, publisher of the Cook Report on Internet Protocol Technology, Economics and Policy, published a quasi-interview with me on his blog. He calls it a "Mini Tutorial" on identity.
It originated in a set of e-mail exchanges on his Architecture and Economy mailing list, which brings together a lot of movers and shakers of the networked economy. The "six identities listed by JP" are in a post by JP Rangaswamy here.
Thanks, Gordon!
