Risk, the game of world domination, is pretty popular among geeks. If you're unfamiliar with the game, the board is a map of the world divided into territories, and the goal is to eliminate other players and occupy the entire world with your pieces. Vincenzo Cosenza's latest World Map of Social Networks, showing which social networks dominate which countries, looks an awful lot like a Risk board, and if it's any indication, Mark Zuckerberg is probably very good at the game.
Facebook may be dominant in countries that speak English (and, increasingly, in countries that don't), but it still has significant competition from other social networking sites worldwide, including QZone in China, VKontakte in Russia, and Orkut in Brazil -- wait, Orkut!? Using Alexa and Google Trends for Websites data, Vincenzo Cosenza has created a world map of popular social networks by country. (Vinco's Blog via THD)
