I recently set up a blog (a pretty private, small scale travel diary to share with close family as I don't use social media) and did some research before I chose something. With no desire for a newsletter or monetisation or SEO or any of those features I still found the experience of spinning up a Ghost containter[1] got me from 0 to a really good and featureful blog.
The composer works well out of the box on a phone, the defaults are fairly sane, and the selection of out of the box themes is pretty well thought out.
In the past I've used Hugo or other static generators for this kind of thing. That's been far more work for a less user friendly result and the mobile workflow for posting isn't very kind even on a tablet.
Great to have the iOS app, an easily convertable human readable and writable format and hang on to your own data.
Going to give this a good look over today. Might think about an Obsidian plugin as well.
