(2006-12-01) Keith Open Identity Hcard

Jeremy Keith thinks that HCard is enough to provide a lot of movement toward an Open Social Networking Model.

Jan'2007 update: Brian Oberkirch has similar thoughts, also mentioning XFN (as Jeremy did) and OpenID.

Jul'2007: Brian is trying to use High-Rise's API and DopplR to manage and republish friends-lists.

Aug'2007: Brian shows has HCard is already getting a fair amount of support.

Brian has a whole series of posts on this.
