The obvious competitors are:

- scheduled radio talk show. They may be inane but they're professional and consistent

- recorded podcast: has the major advantages of being listenable on your own schedule and possibly well-edited

- youtube: same as podcast, but with video as well

- youtube live: the chat allows more people to participate simultaneously than folks trying to get airtime

- discord: it's live and you might even know or get to know all the participants

That's a lot of competition and not much in visible advantages
