What kind of software / tools /styles are behind this blog in the technical sense? I see mathjax, probably some static site generator(?), what else are you using?
- Write in Markdown using your favorite editor (I like Typora; StackEdit is also great)
- Render them in-browser with Docsify (so that you don't even need to worry about setting up a separate build step)
- Deploy to GitHub pages or GitLab pages for free
FWIW I wrote my own scripts to generate static HTML over 3 years, but people were reading it from the first day. So it was just gradually improved over time, Unix style. (It even works on mobile now, after I learned how to do that in the last week :) )
Now, I plan on just having a blog to myself, to post what I've been reading, with some highlights/notes, and for that, a free wordpress.com is way better than anything else, as it's very easy to add different types of media/embed content without a worry, and to use their android app to write on the go if I want.
So really, whatever you use, first decide on your ideal workflow, and then find the solutions :)
