I found that a nice compromise between self-hosting and publishing on a Medium / Substack is using Github pages + Notion published links:

- You get one free site per GitHub account

- I forked https://github.com/academicpages/academicpages.github.io and updated the blog posts to link to published Notion pages.

- This gives you a great WYSIWYG editor and all the nice features that Notion provides (collab edit, embeds, tables, LaTeX, view/edit anywhere).

- Notion handles the SEO too.
