One of the things that seems really interesting to me is how personal podcasts seem to be to listeners. People really spend time custom curating their lists. Many of the problems with podcasts pointed out below don't bother me in the least, but its because of what I tend to listen to, whereas I have entirely different problems I don't see reflected in anybody else's issues.

I think this really speaks to how customizable people's listening habits and needs are.

For example, I mostly listen to podcasts when doing dishes and cooking. And I focus on topics that don't really have a timeliness component, so it doesn't matter if the podcast doesn't release new episodes or I discover it years late.
