i'm a huge data visualization buff, so linkedin's new mapping tool is making me giddy. it literally maps your social graph, creating a personalized infographic of your professional connections. in the tool, you can zoom in and see who each individual dot is, but i actually like looking at the macro view and trying to identify purely based on patterns. my buddy austin is pretty easy to spot. i also have no idea why stanford (orange) is so far away from everything else.
