In spite of previous disavowals of having social networking aspirations, identity link aggregator ClaimID has now added the ability to add other ClaimID members to your profile as contacts.
This is a significant decision because, presumably, every OpenID has an owner. As such, adding one of these “verified” OpenID URLs as a contact to your verified OpenID URL could represent a higher trust level — a stronger “claim” as the lingo goes — than simply using the XFN rel-me attribute to create a “weak” relationship claim. Or so goes the theory.
Meanwhile, I’ve recently been reordering my Flickr screenshot collections and have created a set devoted to adding friends interfaces. If you have examples of similar interfaces, leave me a link to the source and I’ll get them added!
