Now we have podcasting which is incredibly cheap to run. It's incredibly cheap to host. Anyone can do it. It's even less cancelable than telegram channels. There's no app store. It's an audio file. There are plenty of independent podcast apps that do not go through a cloud provider. It's the greatest use case ever for RSS! It's also deeply intellectual, or stupid, or controversial, but it's a million different things to a million different people. In my opinion, it's as close to the true promise of the internet realized as any media that has come along since the 90s.
