Distributed Social Networking
Social Networking Sites are usually isolated silo's, so that individuals cannot port their relationships to other spaces. Distributed social networking aims to go beyond such limitations.
Definition
from Thomas Kalka at http://www.coforum.de/?6302:
"Sites like Videntity and Claim ID are now hooking together Open ID and Microformats to help provide for the first distributed social networking schemes. These are the seeds of something really exciting; the ability to tie single sign-on with portable social networking means we can quickly login to any site and then pull our social networks along with us. Its going to take time and quite a bit more work to get sites to adopt a standardized means for doing this but its inevitable now that OpenID is taking hold."
