This blows my mind:

Each dot represents one of my Facebook connections. The lines between dots show who knows each other. I added my own labels to describe various sub-groups using Skitch.
My pre-college classmates have done a phenomenal job staying in touch over the past 17-30 years. Especially considering that we mostly left high school without our first email addresses.
This helps explain why I find blogging valuable. I’ve met a ton of people that I find interesting because of it.
If you have a Facebook account, you can run your own nexus here.
