long have i admired / followed the work of valdis krebs. he researches the mapping and measuring of relationships and flows between people, groups, organizations, computers or other information/knowledge processing entities. The nodes in the network are the people and groups while the links show relationships or flows between the nodes. SNA provides both a visual and a mathematical analysis of human relationships. valdis is now conducting an analysis of the ryze blogger tribe, a schmoozing cabal i happen to be part of. what a great opportunity to test drive FOAF (friend of a friend) allows the expression of personal information and relationships, and is a useful building block for creating information systems that support online communities. if this analysis goes out of its way to look into FOAF, interesting things could happen. stay tuned.
