Newbie podcaster seeks recommendations

Hi,

I see there are no posts here so I'll ask some questions and maybe it will prompt further discussion.

I'm an old-school broadcaster that would like to use my skills in the podcast medium. I have some ideas for what I believe are solid foundations for podcasts and have the audio production fairly squared, but I want to know what options exist today for hosting on the frugal and diy side. And strategies for multi-platform release, and eventual audience financial support. I see lots of folks putting out their shows across YouTube, etc as well as an RSS feed. Often using Patreon in lieu of sponsorship.

Hoping some experienced folks can throw out some options and what has worked for them. I'd like to not get encumbered in some host that will be difficult to leave later if their terms or service change -as this seems to be a growing problem with all internet media.

Thanks!
