A picture is worth a thousand words...I wanted to try out the new Google Insights for Search comparing the search volume/intensity around the world for: Facebook, MySpace, Hi5 and Friendster. The regionalities which existed before still continue and hold true
Facebook is tops in Turkey, Canada, UK and South Africa
Myspace is huge in the US, Puerto Rico, and Australia
Friendster rules in Philippines, Malaysia and Indonesia
Hi5 dominates Portugal and most of Central & South America including Peru, Dominican Republic
Now the more interesting ones - with respect to the local champions, they're still in the lead in their respective countries:
Vkontakte in Ukraine, Russia and Belarus
But the most eye opening for me was the comparison between Xing and LinkedIn:
LinkedIn is strong in US and India but also in Europe (Denmark, Belgium & Netherlands)
Xing has a clear lead in Germany, Austria, in addition to *China* and Singapore
