Why is Substack so popular?

There are a few reasons that Substack has been so successful. For one, the platform makes it easy for writers to get started. You don't need to be a technical expert to create a newsletter on Substack.

Many journalists and writers are using Substack to build their own brands and reach new audiences. The platform also offers a way for writers to make money from their newsletters.
