I just wanted to post this in relation to Dr. Peterson's speech, he commented on the high ranking of the Korean language in usage and popularity. There is some variation, the World Almanac lists Korean at number 10 while geographic.org places it at 13. Overall I agreed with what Peterson had to say about the potential positive effect that South Korea can have on the world. It was a interesting to contrast with the vastly different realm that is North Korea.
