Peer Index - who are the authorities on the web.



Just been reviewing  @PeerIndex - this is a web site that looks to rate "Who are the authorities on the web?"   Their claim is that PeerIndex helps you discover the authorities and opinion formers on a given topic.


I cannot work out how much is based on what you say about yourself vs how much it is biased towards how much others say about you, nor how sentiment is taken into account.  Obvious is that it is only that material that is public....
