Social networking is not just a US phenomenon. In fact, the United States, is not even the most wired country in the world. Hundreds of millions of people around the world are visiting social networking sites each month and many are doing so on a daily basis. Social networking is no longer a fad but rather an activity similar to checking your email daily.
While attracting global users, specific social networks have a tendency to skew in popularity in different regions. Take MySpace.com and Facebook.com for example, two-thirds of their respective audiences is from North America. But, both are poised and have already started to attract a more globally diverse audience. In fact Facebook has in the works, translated versions of its site.
Bebo.com appears to have a stranglehold on Europe currently, attracting nearly two-thirds of its visitors from that region, while Orkut is the social network of choice in Latin America (49 percent) and Asia-Pacific (43 percent). Friendster also attracts a significant proportion of its visitors (89 percent) from the Asia-Pacific region. Both Hi5.com and Tagged.com exhibit more balance in their respective visitor bases, drawing at least 8 percent from each of the five worldwide regions.

@ tom I love your biznak site, or maybe I love the name more, almost like your taking it to the hizzy. Or perhaps there is a less “urban” reason why it’s called biznak. Any whoo, thanks for visiting, and I agree that they are evolving, towards niche based apps.
