No serisouly, I get the link to the mp3 and play it via MPV in a terminal. If you don't publish an mp3 somewhere, then I'm not going to listen to your podcast. Websites and apps are the worst way to listen to podcasts, because the UX for all of them is like a puzzle (e.g. where's the volume slider gonna be on this website/app and will I find it before it blows my ears out?). The UX for MPV is static; I only have to give it an mp3 link.
There are thousands of sponsor-filled podcasts I could listen to; I'm not gonna waste my time playing three-shells-and-a-pea with an app/website just to listen to your sponsor-filled podcast.
I don't have a cell phone. And it wouldn't make any sense to setup Android Studio just to listen to a few podcasts.
RSS feeds are great.
Honestly, I don't listen to enough podcasts to justify using an RSS reader. Most podcasters have not figured out that they are entertainers first-and-foremost, so most podcasts are a chore to listen to. But, I give an exception to my friends, because I'm more interested in keeping up with them than being entertained.
Yes. I used to drop files in a directory and they would be transferred to my phone with Syncthing, then I would listen to them using an audiobook listener app that had all the properties I wanted from an audio player.
Then I found out that AntennaPod has all these same properties and it's cheaper, faster, leaner, prettier, and the fact that it fetches the episodes automatically for me is good, not bad as I originally thought. Also having each episode metadata and just having them organized overall is really good.
