Over the years, I have conducted numerous interviews and moderated countless panels at various live events, such as South by Southwest and the Texas Book Festival. Here are three that were saved for posterity. (The first is particularly notable: Casey and I were, essentially, the opening act for Barack Obama, who was in an unusually diffident mood that day. After the dual event was over, a number of audience members buttonholed me to say that our discussion was the more interesting one.)
