I disagree. Maybe you'll remember it not as well if you don't do exercises, but there is no reason you can't learn from a blogpost (which is trivial to prove since you can just copy-paste the contents of a book in the form of one or more blogposts).

What your parent comment meant was that it is not possible to learn well from typical blog posts like this that try to condense the subject into a 3000 word article. Of course, if you copy-paste the content of a book into a blog post, then parent comment's point no longer applies.

I'd say it still applies, even when reading a textbook going through the exercises is crucial
