Roy, publications can give you leverage.
If you’re just starting out and have no followers, a publication can give you a boost. For example, if the publication has 100,000 followers, you know at least some of them will see your work. Some of those who see it will read, comment, and clap. And if your work resonates with some of these people, they’ll spread your ideas.
This works on Medium and on popular websites. Be sure you target places that share your worldview, and the doors of opportunity will start opening.
Thanks for reading and responding. And good luck!
