Tbf if you want a big following for ads and such you need to use whatever has the people on it.
Lemmy is great for personal hobbies and enjoyment, but not running/advertising a business (which I assume the podcast is).
And it should probably stay that way? Not sure.
But I’m of the opinion that stuff like Instagram/Fb/X will always be around, but I’ll stick with things like Lemmy for personal stuff.
Agreed, love it!
