They're migrating to facebook. Social networks don't make sense if they're nation limited, be it de facto or by design. People will migrate to the biggest most popular one eventually. I suspect facebook is just the best (by some people's standards) social network and social networking eventually falls into a natural monopoly.

If you would have said Belgium, I would have been able to say this…

"In the 1970s, economist Edmar Bacha popularised the term "Belindia" as a description of Brazil: a little bit of Belgium and a lot of India, the country was very rich for some and very poor for most."

Speaking of rich and poor, data from the recent Brazil x Chile World Cup game shows that most Brazilian stadium attendees were white (67%), mid-high/high class (90%), and well-educated (86%). Ok, now I'm officially off-topic. Carry on.

but to google, 200M means their possible market size is really a fraction of that. Imagine 30M MAX users, assuming super high penetration. Google wants to focus on BILLIONS of users, not tens of millions.
