Podcasting has the vibe of the early DIY web. It's largely independent and isn't "owned" by an oligopoly unlike social media. Indie podcasters sometimes struggle with distribution if they get popular. Lastly, it has a major vanishing content problem when old orphaned podcasts disappear from podcast hosting services but may still be interesting.

It would also be fairly easy to write a web-to-SAFE bridge server that allowed people to add podcasts hosted on the SAFE network to regular RSS podcast players. People could run this themselves or run open ones on the web, with the latter amounting to a community run CDN.
