I really like how Substack is evolving as a platform for content creators, especially for writers. I kept my account open after moving from Substack to Ghost.org. You may disagree with the fact that you don’t really own the content or whatever, but Substack is evolving quite a bit. If I compare the features set when it started and today, it is night and day. They are really killing it. As a member of Substack (free) and Ghost (paid), I would say Substack > Ghost.
I would really like to find a niche use case for Substack. And I thought that 2023 was the year of focusing more.
