Co-founder of Banter, https://banter.fm. We make podcasts easier to share and have conversations around.
We've basically built a BYOC (Bring-Your-Own-Content) social network. Publishers host an RSS feed and remain in full control of their content. We don't try to assert copyright or anything over it. We don't even host it. We just enable conversations and sharing of that content (we even generate videos for sharing on other platforms that don't support audio well: https://twitter.com/stevekrenzel/status/1040746982615076864)
Some of the best content being produced today is in podcasts. Everything from comedy to news reporting. They're a great way to help people stay informed, learn new things, or just get a laugh. So if that counts as "truly mattering", then that's why it truly matters.
