It looks I need to take a look at micro.blog for hosting a podcast. I have been looking at Castopod for hosting for a while, but i need to get on this. I have been hosting a radio show on FM radio for a few years, and now I have 200 or so episodes that need to be set out into the wild.
I like the idea of using the fediverse for hosting my content, and this might be the way to go.
