As of writing this post, below is the list of countries by number of internet users

India has a penetration of just 12.6% (but already at rank 3) with the number only slated to grow steeply with the slew of cheap internet enabled mobile devices flooding the market and the lowering costs of internet access. The US has more or less already reached its limit with 81% and its safe to say that the Chinese government's policies will not allow China's 42.3% of users to engage with the rest of the world through the internet. It seems inevitable that Indians will form the major number of netizens very VERY soon.

So, you'd better expect a LOT of fraaaaaaandship requests in the near future!
