A good ER database textbook illustrates normal forms much better than a blog post.

I find that textbooks focus way too much on the strict CS definition of the various normal forms as opposed to practical examples.

That's a sweeping over-generalization. I said find a good textbook.

The poster said "I find that...", which is equivalent to "In my experience...". How is someone posting their experience the same as making a "sweeping over-generalization"? They never flat-out said "ALL textbooks".

Also, surely if it were not accurate you could easily drop the name of a good textbook without any trouble, since you apparently have enough experience with them to make the distinction.
