Most listeners see Apple Podcasts as "good enough", but I find it confusing, and other applications follow the same approach with one or two "tweaks" that are not worth sacrificing features or adjusting to a new UI. I'm still optimistic that Spotify can get their act together (since they have the resources and incentive), but they haven't done anything dazzling since quietly adding a podcast section years ago.
It severely limits the capabilities of the medium, and yet no one seems to think anything is wrong. I understand this structure is a result of RSS serving as the backbone of "podcatchers", but everyone would benefit from a bit of lateral thinking.
