Valdis Krebs has mapped his twitter network, in the graphic above. Mine would be more complex, I think, and would have to capture my f2f, IM/VoIP, blog and Second Life networks.

My Blogroll has several hundred people in some 30 networks, with even more connections. It would be interesting to see the whole map. I suspect it would show that most of my networks are well connected internally with each other (cliquish?) and that, while men on the whole have more connections, women have more diverse connections. It's been interesting to see my twitter readers 'talking' to each other across my networks, making new and unexpected connections.
