It’s all about credentials. But not the credentials someone else gives, but the credentials the editor gave. Most magazines write about someone or let them write for them because of outside credentials.
Publish a magazine where the only credential that counts is what the editor thinks. Only articles of personal judgment are published. The people profiled are chosen because the publisher and editor regard them highly, even if they are unknown to most of the world. It’s an entirely personal (but explained) point of view in each and every article published.
