I guess it depends on the type of person you are and how you learn best. In my case for example, I learn better by coding while following a video than when I have read through a massive blog post (Which involves a lot of copying and pasting). That said, text format is great in book form because you can easily reference a concept without having to scroll through an endless page. The only downside with books is you have to wait longer for the content to be updated. Just my 2 cents.
