The most striking things to me when I started reading the Essays, is how much it reads like... A blog.
Variety of topics, general consistency of theme, a tone that is surprisingly conversationnal... And the bombardment of references, in jokes, quotes, etc... that you use to create connivence with your reader.
Also, in the end, if you were asked what Montaigne was famous for, what he actually did, _beyond writing his blog_, you would be... hard pressed to answer.
Still, I would probably lurk his substack, and watch his stand up on Instagram.
