Worldwide Social Network Market Share

Worldwide Social Network Market Share - O’Reilly Radar
I’m not surprised to see that Hi5 is the most popular social network in Thailand. Even I who don’t care much about these things got convinced into creating my own profile on HI5. However, I still don’t understand its benefit. Why would I want to use it?
Anyway, the map itself is interesting enough. Thailand shares the same interest in HI5 with Mongolia, Tunisia, Portugal, Romania, Columbia, Ecuador, Peru, Honduras, Guatemala, Nicaragua and Costa Rica. hmmm
