Don't know if I have it in me to host my own RSS/Chapters but that's pretty smart on Podcasting2.0 where as it references a file outside the feed, chapters/content could be changed at any time but don't think I have it in me to get that technical.
I'm surprised that in the wider podcast community there's not much interest in chapters, listened to some podcasts recently where over the hour a couple of images would have added to the experience. After hearing about CurioCaster on Podcasting 2.0 have given it a (very basic) go using Buzzsprout. I borrowed a Gif as ones I tried didn't work so was wondering if specific criteria to get Gifs working https://curiocaster.com/#episode-cG9kY2FzdDo0MTE5ODE0JmVwaXNvZGU6QnV6enNwcm91dC04OTkzMTc1
