OpenFriends is about more than just your contacts: it's about a distributed social layer for the web. Add your friends once, and take them with you, everywhere you go.
When you join a social network community site, you have to start adding your list of friends one by one. Either that, or you have to grant them access to your email account. In the end, it is either a real pain or a dangerous privacy violation. Besides, doing the same thing over and over for each new social website has turned the experience into a constant hassle.
OpenFriends solves this problem by providing a way for you to share your list of friends that respects your privacy.
Right now there is one way of easing the pain: microformats. You can have an hCard in some website, along with a list of contacts in XFN format, and point to that URL when signing up to that new social network website. There are many sites that already provide hCards and XFN lists for you, like Twitter and Flickr, and there are also some sites that are ready to consume that information. What is the problem then?
Even though both XFN and hCard are standardized, each provider exposes the set of contact data of its preference. Besides, as the profile and the list of contacts are publicly accessible via web, there are a lot of privacy issues at stake. In the end, the XFN list shows only a list of related usernames within that website, and it is usually not enough information for recreating your network of friends somewhere else.
Please refer to the openfriends website for more information about the initiative and what are the ideas behind the implementation.
