> Rather watch than read?
Hey, I get it - sometimes you just want to kick back and watch! Check out this quick video where I walk through everything in this post
Me neither. But some people are dyslexic or non native speakers (it's common to have listening comprehension better than reading comprehension when learning a language) and have to put more effort into reading than I do, and some people genuinely just prefer video.
I think it's decent of the author to provide a video for these people.
