Podcasts where people are just shooting the shyt are gonna run out of shyt eventually. Only so many tales you can spin in a closed group. Then you'll have people who have no business addressing current issues doing just that
Either they need guest and making the whole show about them or have a specific topic for each episode. The great thing about having a specific topic is that the back catalog is worth revisiting.
I just got finished listening to What Had Happened Was with Open Mike Eagle where he interviews Prince Paul and goes through his whole career. Something like that doesn't have a used by date. It was fire and I learned a lot
Frankly, those chatty patty podcasts held people's attention for a shameful amount of time.
