why is friendster so popular in Asia?

[riogangsta]

It's all a "momentum" issue.
Friendster was big here, but never got momentum. Not enough user signed up.
You need momentum to sign up enough people and have them build such a large network that would make it nearly impossible to migrate all his network to a different one.

Myspace and Facebook had that momentum going here. It would be quite hard for American users to migrate all his network to friendster.

On the other hand, Orkut is HUGE in Brazil. Same issue. It had momentum and enough users signed up in Orkut that would make a hassle to migrate all your network to another service.

Same applies to friendster in asia
