i don't think that big, powerful countries bringing civilization elsewhere has really been a successful from the point of view of the people whose civilization is apparently being imposed upon them. There's no magic bullet or special procedure to get called by reporters. Sometimes you just want that juicy quote, and you go for the same person over and over again. i have instituted a policy where i do not repeat guests other than myself on my solo episodes. But there are some real benefits to having a set number of favourite guests who would make great panel discussions. This is not to say I'm going to start saying 'yes' every time someone asks me if they should be brought back as a guest in another episode
