Podcasting has been around for 20 years. Many revolutions have happened since then: DSL connections, smartphones, social networks, artificial intelligence everywhere… But Podcasting stayed still and its decentralized architecture resisted to the big corporations. In this talk we will show how the Podcasting 2.0 community is reinventing Podcasting by adding tons of new features, while keeping all this interoperable. We will quickly demonstrate how this actually works with Castopod, an open-source podcast hosting solution.
