Thanks for the good post, I think I need more people like this. I myself do not work with fonts, however, after reading the article I wanted to plunge into this topic a little closer. I read before this one good article on another site, https://writeabout.tech/design/75-best-free-fonts-for-designers-2/, I think it will be useful to read.
