It would be useful if all radio topics could be hosted and discussed on a dedicated fedi instance. The lemmy.radio description is constrained to amateur radio:
“A lemmy instance for amateur radio enthusiasts and communities.”
There are no communities anywhere in the fedi for FM or AM radio apart from !radio on LW (a Cloudflare-centralised instance). And that community is strangely constrained (tech support/user inquiries unwelcome according to the sidebar). DAB radio has one community strangely placed on a “UK centric” instance: !dabradio@feddit.uk.
My reasoning against it would be that this instance would become diluted.
The best part about federated services and lemmy is you can start a community on any open instance.
lemmy.radio is for amateur radio only, however. Both membership and community creation.
