Distributed Social Networks [opencontent.org]
David Wiley posts about fully distributing the social network. This basically means empowering blogs or other personal Web sites to make the connections directly, without a centralized service such as Facebook. One of the ideas that makes this work is URLs are people, too.
Standards like OpenID, XFN, and hCard can be used to tie all of this together. The DISO-Project is working on the code to make this happen now. They are starting by building on Wordpress, but any Web platform should be able to support these formats.
For a short introductin to some of these ideas see 4 Technologies for Portability in Social Networks: A Primer.
