How Has Korea Become Internet Powerhouse?

This is a good question...but I suspect that it comes down ultimately to economics, not "the culture and emotion of the Korean people." This strikes me as a ludicrous explanation that verges on no explanation at all:

The rapid increase in the number of users can be attributed to the dramatic jump in the number of computers in homes and a trend toward computer education.
But the primary reason why the PC communication culture flourished is that it matched the culture and emotion of the Korean people and their need to communicate with one another.
This can be seen by the PC communication culture of clubs and boards.
Boards, a forum to discuss and exchange information, developed into the two main models of Korean Internet services: knowledge search and reply culture.
In addition, clubs, which brought together people with similar hobbies, were the beginning of Internet communities such as cafes, as they called here.
