Being something of a purist, I tend to keep coming back to angle #3 and to avoid the other two.
I really want lots of people to enjoy the show. But more than that, ultimately, it needs to be something I enjoy (creating and listening to), and I don't want to do anything that will make the show less enjoyable -- not for growth/promotion, and not for monetizing, either.
And yet, if it was bigger and more self-supporting, I'd be able to spend more time on it and (I'd like to think) improving it. The classic scenario.
