Live Streams / Online Radio
Castopod needs an ability to host live streams. Much like Peertube allows for live-streaming video content.
Live streaming is a powerful tool for both making new content and community management. But live streaming video is expensive, and audio streaming on a video platform seems like using a wrong tool for the job. The ability to host live audio will boost the adoptopn of Castopod and podcasting in general. It will just make it easier to do. Anyone can be a radio host.
In Russian Fediverse, we have a bi-weekly live talk show called "Regular Expressions", around which most of the RuFediverse community is organized. It's hosted on Peertube, but only because it was the only platform to offer live shows. If Castopod existed a year ago, and if it had ability to live stream, we'd have chosen Castopod.
