Given the nice interest in the taxonomy of Social Network Services, may I ask Tracy Kennedy and other thoughtful users to contribute taxonomies and other useful things to the Wikipedia article "Social Network Service". It's in need of such help. http://en.wikipedia.org/wiki/Social_networking_service Thanks. BTW, there is also a more fully developed article on [[social network]] -- focusing on social network analysis.
