So this falls in the totally “BAD ASS” category.  A free online tool called Nexus is an interactive social network grapher that visually displays connections between Facebook friends and their shared interests with one click.   Below is the output of what my social network of 522 friends on Facebook visually looks like:

The application allows you to hover over any node above to view friend connections. You are also able to click a node to view similarities with other friends. Finally, friends with darker connection lines  have more interests and groups in common.

Pretty cool!
