I'd never heard of Ghost.org, but looking at their website, they appear to be much more than just a free newsletter platform. It's not what I'm looking for, but it does look pretty cool for somebody that needs a professional publishing stack. They show their competitors as Medium, WordPress, Substack, and Patreon, and if I were considering any of those I'd give Ghost a closer look.
