All these podcasters know each other. It may as well be network television
It feels like an obligatory side income stream for every "creator" out there, one that only requires them to turn up in front of a microphone and banter once a week. The signal to noise ratio is way off. I don't want to start of with 15 minutes about how the creator's week was.
Nowadays I realise that there are podcasts that are actual "productions" (educational or otherwise), which I would enjoy a lot more. I'm probably missing out on a whole medium. But I haven't come across that many yet.
Think of it like replacing niche, once local-only radio programs. Those too aren't very high production because of resource and time constraints. It won't please everyone and doesn't have to.
