Visualizing your Facebook friends’ geographical location
The basic version breaks down the list of your friends by location, gender, relationship status, and list membership. The advanced version of the app features drop-down menu of filters based on interests such as religion, books, music, and work history.
I was pleasantly surprised to see how broad the geographical spread of my Facebook friends is and decided to further explore their origins. It turns out that the majority of them come from hometowns different from their current cities. Switching back and forth between the home town and current city makes for an interesting graph of Facebook denizens’ migration. See for yourself at http://apps.facebook.com/wheretheynow.
