and several more that are "old" - as in they do not add new podcasts any longer (perhaps on a different platform that I'm currently using). When I finish up the ones that are old, I have several others in the wings that I'd like to give a shot but not until I get this list pared down (I have other topics I also listen to such as beekeeping, farm business & marketing, herbs, cultured food, goats, etc).
I use an app called Podcoin. It pays you to listen (very similar to a cryptocurrency but only for that site). If you stay on the basic then it will "pay" for up to 6 hours a day. However, the more I listed the more it gives bonus podcasts and also begins to pay double per minute. I haven't been doing it too long so there could be other bump ups I don't know about. I'm using it to acquire a few gift cards for Christmas, along with several other apps I use to "earn money" for gift cards just for walking around - which I do anyway just taking care of the house and farm.
Sorry to get off on a tangent there!
I also listen to Stitcher and YouTube for podcasts that are not on Podcoin.
