Discoverability is by far the biggest problem any media company faces (and podcasters are a media company). Millions of minutes of viewing, listening, and reading content are created every day, and the barriers to creating content have never been lower. The biggest problem podcasters (or anyone else in media) face is that created content goes into the void never to be seen or listened to. No ideal solution exists for this, as people have a finite amount of attention, and more content is created than can be consumed in a day.
