I am of the opinion that writing can’t be taught. Since there are no real rules about writing anyway, I have always been suspicious when I come across writings about writing, especially those which have rules in them. Mostly I ignore them, not just on Medium, but also on blogs, twitter, etc.
Though a while ago, I did reflect on and document the trouble I went through to write two novels and put it somewhere on my non-Medium website. You should not read that, because it’s silly.
