I listened to This American Life from the first episode until they abandoned their mobile app. It was so easy for me to use it and mark things. I even emailed them about it; they said it cost too much to operate. It didn't make sense to me. I guess I will go back to listening to them again on Apple Podcasts. I even exported my playlist with data from their old app; not sure how I will sync with the Apple Podcasts app, though... Another challenge for Fable to solve, I guess.
