Digrii is a social network that allows you to discover the degrees of separation between you and the rest of the world. Digrii works on the six degrees of separation theory.
Once you become a member of digrii you can discover your degrees of separation with people all over the world on a Google Map. Your connections are shown on the map by lines connecting you with other members you know. Digrii will also tell you how many people there are between you and other people.
