Last month's Facebook: mapping earth post provoked some discussion about why the north of Asia was AWOL and why Facebook, which seems to offer something for everyone, hasn't managed to penetrate into the huge hunk of landmass that dominates one half of the world map (read the previous post for a refresh).
The empty spaces occupying rural Africa, the Amazon and central Australia are easily explained away by geographical location, as too are those countries with a lower GDP. However, the Asian countries with captive audiences and technology coming out of their ears have kept Facebook at arm's-length through censorship. The uber-talented guys at Information Is Beautiful have come up with a very pretty and easy-to-digest analysis of such censorship. Below are the Facebook map from Paul Butler and the censorship map from David McCandless. Draw your own conclusions.
Anyway, here's the link to the full visualisation. One particularly information-rich diagram is the good old fashioned venn diagram showing the various overlapping reasons for internet censorship in the different regions. It's pretty cool. Have a browse, learn something new, drink a beer (just because).
