It really doesn't. An experienced dev could recreate the core features in a web app within two weeks or less.

The more difficult part:

- Understanding the work that goes into making and releasing a podcast

- Figuring out that a step in the process is not being done efficiently

- Determining a balanced set of features whose delivery and maintenance cost is low enough that people in industry will benefit from paying for them

- Marketing your software to potential customers

- Convincing them that they will benefit from purchasing your software

- Maintaining the software to satisfy your customer base

- Exploring and releasing new features to stay ahead of your inevitable competition if the product is successful

- Taking the initial risk to start development

But everybody here knows that already.
