  • [TIL] Switched Podcast App to Overcast
    Actually, the biggest problem with listening to podcasts should be "how to find your favorite channels?". I highly recommend trying Castbox. There are many recommended channels inside. - Source: dev.to / over 6 years ago
  • If you want to marvel at just how racist and insecure Ben Shapiro is, I highly recommend listening to Behind the Bastard's readthrough of his military-grade stupid attempt at a novel
    Personally I searched Spotify. An easier way, because it sorts by date is a podcast app called castbox. Source: almost 4 years ago
  • Started listening to the new OPR podcast Jackals and Daemons. Highly recommend!
    Is it possible to upload it to https://castbox.fm/ (it's my go to podcast service)? I've been hoping someone would start an OPR podcast for ages :D. Source: about 4 years ago
