Hosting on Hugo/Netlify is kind of a good solution, but I feel like there needs to be a completely free, managed version. Setting up Hugo/Netlify is mostly simple, but it's one of those things when you don't want to deal with updating your local tech stack vs a managed service.
I feel like Substack is slightly better, although it still does lean towards "subscription" first services (but at least it's per user / patronage type model)
