Here’s the uncomfortable truth. A lot of writers saw their subscriber growth drop 80-90% in 2025. They kept publishing. They kept writing good content. But the growth stalled. What happened wasn’t a quality problem. It was an adaptation problem. These writers were still operating on the old model: publish a post, share it on social media, hope people click through. Meanwhile, Substack was redirecting discovery to happen inside its own ecosystem and the writers who weren’t showing up there became invisible. I watched it happen to writers I respect. Smart, talented people who just didn’t adjust. The ones who did adjust: Their growth accelerated. Because when you work with the internal discovery engine instead of fighting it, you’re accessing an audience of 35+ million active users who are already inside Substack looking for content.
