They're both great writers.
I think this concept a nice way to bring two people together at a time to genuinely get to know each other better or share a little more about themselves than they normally would. Them being brothers sure made this real and meaningful. AMAs seem to be a bit inefficient and off the cuff, so something like this helps people really sit and think with less pressure.
I'm going to try to make this a running series if I can assemble enough people who are willing to support the spirit of the concept.
Thanks for the feedback.
