@matigo There just isn’t that much. Marty McGuire has the audio version of This Week in the Indieweb, which is fun if you haven’t read the page. Manton’s Timetable and Aaron Parecki’s Percolator microcasts can be a bit insider if you are not already involved. I don’t know of any others.
I’d be game to try something, but it would be difficult to structure. A sort of Ask Me Anything with a stable of rotating guests might work. And the new version of Anchor might make it easy.
