All of this would be achieved in a People Browser centered around the mu ideals - and it's continuously more difficult the more social networking sites are created with different vocabularies.
a peer to peer profiling system completely rids the need for *any* facebook/yahoo360/myspace/insertnamehere profile. all you need is a presence ID (OpenID compatible) and a presence server (if you want to keep your IP addy anonymous) like yahoo/AIM/ICQ or just an p2p IP presence broadcaster like Solipsis
At this point, "friend" relationships remain unique to the social networks. The web still lacks a generalized way to convey relationships between people's identities on the internet. The absence of this secret sauce -- an underlying framework that connects "friends" and establishes trust relationships between peers -- is what gave rise to social networks in the first place. While we've
largely outgrown the limitations of closed platforms (take e-mail or the web itself), no one has stepped forward with an open solution to managing your friends on the internet at large. We would like to place an open call to the web-programming community to solve this problem. We need a new framework based on open standards. Think of it as a structure that links individual sites and makes explicit social relationships, a way of defining micro social networks within the larger network of the web.
[There's the Friend of a Friend (FOAF) framework actually, for a common vocabulary, and quite frankly you dont need a vocabulary - everyone creates their own on the fly and it's entirely your own to use and manipulate (subjective) and objectivity is acquired over time as you share it with your friends. There's no use trying to establish what the DENOTATION of 'homey' is when EVERY relationship definition is by definition CONNOTATIVE (triumph of the subjective). There's no difference here between defining a relationship and tagging and folksonomies. I personally don't share my tags, because my tagging style is completely my own and pointless to share - I hate the wisdom of crowds - I think they're stupid. I love the wisdom of my peers however, to varying degrees]
