Writers who do this aren’t creating a writer profile that their readers can understand and trust. This leads to their followers ignoring new articles in their feed and the Medium algorithm learning that the writer isn’t providing the same value as before.
Mmmm... If you write with an algorithm in mind you'll churn out algorithm-friendly drivel. Sorry for being blunt but writing, as an art, is a creative activity, that starts inside the writer. That means, it starts as an individual act. It can be done collectively, but it starts from within. Algorithms don't care for your craft. They only care about numbers.
Finally, there isn't and there shouldn't be an either/or in writing. It should be both/and. You can be both a lifestyle writer and a thriller author.
