I am not a fan of facebook, hell, I am not even a user of facebook. I cannot deny though the revolution it has caused in social networking and global communications. On the other hand, I am a fan of maps and graphs. I enjoy looking how nodes connect and try to digest the info. A facebook employee recently showed a graph the shows visually how people are connected globally on facebook.
It is very interesting to see the spread of connections throughout the map. Dark areas, light areas, all have a meaning and an explanation. For example the whole of china is dark since facebook is not allowed in China. Check out how different parts of the world are connected. South America is mostly connected to Spain and Portugal, which makes sense since they speak spanish and portuguese.

This guy has the biggest pool of data in the world. Facebook has more than 500 million users which is basically the whole western world. Having such a dataset is something that you can almost envy. On the other hand, one corporation having such a dataset, about people and how they connect, is not something to be taken lightly...
