Yay  AntennaPod! AntennaPod is pretty and it consistently loads podcasts' artwork. It also has useful sharing features and I like the way that it organizes episodes. My only complaint is that it exhibits odd back-button behavior  often bringing me back to Android home instead of the previous page in the app. Also  playback occasionally stops when running Waze. This behavior is rare enough that I haven't bothered to investigate.
