Using del.icio.us network explorer

I have been using delicious network explorer to try to understand better my delicious network. This has proved fascinating, as I have discovered social networking 'gurus' (hrheingold, cshirky, choconancy and kanter) as well as important centers for social justice in the context of Africa (BlackLooks, BeckyFaith). The social networking people generally have a very large fanbase and relatively small network. Choconancy has both. I think as I dig deeper I can establish more effective interactions which are difficult when looking at a list of users.
