What I do is get a legitimate Pyongyang working telephone number, then do a few digits off on the end, and call, and see if if goes through and who picks it up. An average North Korean citizen in the past has been snagged this way. One even spoke a small amount of English but was probably not too happy about talking with an "outsider" which is not sanctioned outside of official DPRK tourist guides/watchers, government spokespeople, hotel workers, etc. In fact, one can get in somewhat of trouble. That is why I am a bit hesitant to draw an average Pyongyangite into a discussion has it could have negative reprecussions for them. Calling the hotels and news stations will generally not get anybody in trouble. We have to be sensitive to the brutal, paranoid system these people are under, and how they will send someone to a Auschwitz death camp in the snap of a finger with no trial or reason.... Later we will see if Kim Il Sung University picks up, such as in the English language department.
