The question that many people ask themselves is what is Substack used for besides newsletters. The fact is that it is a full-fledged publishing ecosystem of writers, journalists, and creators who wish to distribute content to a reader. It is used by people to host newsletters, essays, podcasts or even a discussion within a community. It is a place that you have your own audience and you are not controlled by advertisements and algorithms. Substack is reinventing the process of independent creators publishing and monetizing their work.
