If you mix the creators into a single timeline that sorts of turns it into a voice-only TikTok. I've been toying with an idea that's more of an async version of the Marco Polo app but for podcast-type content. Async bites of a single podcast episode which may involve one or more contributors continuously adding to the episode/discussion. Does anything like either of these exist already?
