What Microcast.club was
Contemporary IndieWeb material describes Microcast.club as a directory or webring for microcasts: short-form podcasts that could remain on their creators’ own sites and feeds. The directory supplied a shared discovery path while the creator kept the canonical publishing surface.
That model matters because publishing and discovery were separate. A show could keep its own website, audio files and RSS identity while a directory helped listeners find it and move on to another independent show.
