We have a great first mover advantage, and aside from that we have a willingness to hard fork. Bitcoin has largely failed to incorporate the innovations of its competitors, but Steem can do exactly that as long as we retain this political will, and the effective decision making system we have now.
IMO, South Korea at 3% of the site traffic is HUGE. It seems that they don't really use Google over there, www.naver.com dominates search. And since there's no 'Naver Trends' we can't dig into Korean search trends effectively. The kr tag is clearly growing quite effectively though.

It's Metcalfe's Law in action, although a different form of it. When your own personal social network are on Steemit, it adds so much more value to you personally because now there's no need to use the other social networks to communicate with your friends.
It will get even better if Busy.org catches on because you can send private encrypted chat with your Steem keys (private communication is seriously lacking on Steemit).
