As writers, we all get that. Then I think about the Scarecrow saying "people without brains do an awful lot of talking". So it stands to reason that we have the opposite problem. HAH.

Best of luck, I too concider a pod cast of some form and also worry that I'd be lacking in ideas.

I may combine my love of sailing and Star Trek to have a niched down program, rather than trying to stick to one subject. Years ago, when I was a handyman, I had a customer who was a reasonably famous Christian author that combined sex and religion. He's made quite a decent living with that combo. I figured if he could connect that, I sure could connect all sorts of things. :-)

All the best.
