Facebook & MySpace dominate the Americas, but not the world!

We came across an interesting graphic on O'Reilly Radar that provides a very visual representation of the popularity of different social networks across the globe. While MySpace continues to dominate the US and Facebook dominates England, Canada and South Africa, the rest of the world tends to hang out on social networks that are less well known in the US: Live Journal dominates Russia, Orkut is the leader in Brazil, and Hi5 is popular in much of Southeast Asia. This indicates that companies wishing to market to social network users should be careful to identify which social networks are popular with the particular geography and demographic that they are trying to reach.
