This was my first facebook app. It helped you visualize where most of your friends & family live. The new facebook graph API is simple and I really enjoyed using it. As always I love the ExtJS framework and OpenLayers.
UPDATE: Shortly after creating this app, Facebook’s terms and conditions changed and friend locations were no longer available unless those friends had installed and authorized the app as well. This significantly reduced the effectiveness of the app and I haven’t explored any alternatives since.
