Visualizing your business network can give you some interesting insights about where your connections are.
This is a map of my personal network on LinkedIn. (You'll see me in the middle there.)
What I find most interesting is that large blue mass to the the left. Those links are to individuals who are entrepreneurs, angel investors and startup guys. The green links are the same but differ in location from what I can see. The pinkish links to the right are my current connections through Freelance MD.
If you're looking for a nonclinical job or building any business on the side, your business network is the place you'll start.
