Touchgraph

I just noticed a lot of my friends on Facebook are sporting these new Touchgraph pictures, so I had to go check it out... it's an app that maps your social connections based on your friends and the photos you've been tagged in. This is pretty cool - I've seen similar applications but they were pretty elaborate and not available for free. The other thing that's great about this is the sheer amount of data available in a social network like Facebook - you could never get that by conducting surveys. Go check it out, it's definitely worth playing with. You can look it up on Facebook or just go to their site:
