So I ended up going with micro.blog. I don't love that it's American. But it stores my stuff in Europe, it's easy to export and back-up the blog if I have to move elsewhere, it does cross-posting, and it lets me centralize a bunch of other stuff (like my bookmarks formerly on tinygem and my to-read list formerly on goodreads). Hence the name: stuff.interfree.ca
