Agreed. Even when you own the space, from time to time you revamp some major subsystem (e.g. your typesetting pipeline) and it's a pain. But at least its on your terms.

If your hoster shuts down, you're looking at lot of work to port your stuff elsewhere.

That said, there are a lot of things about Substack that I like. They're doing a pretty good job of it.

That said, I still 100% plan to host my own stuff. :)
