If comments are to take off, there needs to be an easy way for a user to post a comment within the app. I don't care if this is decentralized or not.
I would love to see someone make an open source api server than any podcaster can host using Digital Ocean or any Shared Hosting site with good documentation on how to get and receive comments from the api. The api should be consistent across podcasts, but each podcaster has control of the comments hosted on their server.
Intended for all stake holders of podcasting who are interested in improving the eco system
