I'm such a copycat: I saw Karen Blakeman's visual LinkedIn network on her blog, and thought I'd see what mine looked like...
I've taken out my name at the centre, and the shareable version strips out contact names, but I seem to have 3 separate worlds - orange is workmates, past and present. Blue is personal/real life contacts, green is online/social networks contacts, and pink are library-but not via-social-network contacts.
Methinks you can see that work and social/personal don't really overlap in my life, although some of the colour coding, as Karen says, seems to be entirely random.
But it's still quite pretty, all swirly and stuff!
