Honestly it's not that hard to stay out of Balaji's way -- he'll literally talk for ten minutes uninterrupted, pushing and popping items on the stack, delivering book chapters basically verbatim. He somehow never loses track of where he is or what he's saying.

The guy's clearly a genius. The downside is that I've never heard him interviewed in a way that was actually a dialogue, vs a monologue. Stick a coin in him and he's gone, world's easiest interview.
