Podcasts and podcasting have been around a while, but seem to be going through a renaissance of sorts -- partly enabled by connected cars and other technologies. But how do we discover podcasts; is the ideal atomic unit the show, or an individual episode/topic? What makes a good podcast? And given their intimacy, how can brands and communities engage with podcasts? We discuss this and more in this oh-so-meta episode of the a16z Podcast-about-podcasts. And to help us do that, we invited longtime podcaster and radio host Roman Mars -- of the highly regarded design show 99% Invisible -- as well as fans (and now curators of) podcasts, Ryan Hoover and Erik Torenberg of Product Hunt. [Along with, of course, your a16z Podcast producers and hosts Sonal Chokshi and Michael Copeland.]
