Mapping Facebook

Mapping social networks isn’t anything new, but I find this lovely map of Facebook users in the BBC to be incredibly striking.  First, because it’s obviously beautiful.  Second, because you can use it as a proxy for the digital divide.  The map details connections between friends on Facebook with the bright points at the end being conjoined pairs of friends.  The spidery lines are the connections between those pairs.  It’s pretty striking that it creates a pretty good replica of a map of the Earth.  However, there are clear missing points, most notably lower population and lower wealth places.  China is the really interesting hole because of their restrictions and not because of wealth or population.  It would be really interesting to look at a finer scale map with some demographic data on top of it.  Are there places in even populated areas, such as the US, where Facebook just isn’t that popular?
