Considering to join a lemmy instance not the least because it says “you can also blog on lemmy” (https://join-lemmy.org/docs/users/06-other-features.html?highlight=blog#lemmy-as-a-blog) I have one question though:
Can I have MathJax or KaTeX to do formulas?
I am not aware of any such feature on Lemmy Look into https://dokie.li/ or WordPress with ActivityPub plugin and LaTeX plugin
That won’t really help with others seeing the content correctly, though.
