Spend time in a Korean office observing teams and you'll find many workers surfing the Internet.
On one level, workplace norms require they be at their desk long hours--even if they have little workload or completed their projects. Surfing allows them look busy at their desk and pass the time.
I have found that surfing is popular during lunch hour and in group meetings.
Koreans spend considerable time on the Internet. In a previous Blog posting I listed some top eMedia sources. (BTW Korea newspapers like in most global markets are finding paper edition sales dropping annually).
Here are some interesting Korean Blogs to follow.
DPRK Studies ( North Korea focused)
Korea Vision ( Great insights by Leonid Petrov)
The Grand Narrative ( Gender, advertising, and popular culture)
