My numbers here are good but I do self promo fairly consistently. I don’t know anything about substack but may check it out. Briefly glanced at Newsbreak but didn’t see how that was relevant since, from my brief glimpse it’s all about news stories local to a writers area.
But, time is the real issue. Between freelance and personal writing, there’s no time remaining to diversify with any consistency. I tried Simily but that seems like a bust and Vocal read rates make self promo a waste of time.
