What text is educational or not educational?!

There are many texts that would be considered either eduactional or non-educational. Many texts are educational in some way, and some are purely for entertainment purposes. If we really think about it, however, we can come to realize that even texts written for the soul purpose of entertainment can be used for educational purposes. According to that logic, every text is educational in one way or another.
Text is deeply rooted in educational purposes. Some texts are blatantly educational, throwing knowledge at you in a distinct, clear, and precise method in order to fill your mind with the text's intended subject matter. Other texts may seem less educational, but it is educating us in a more camouflaged fashion. Advertisements, for instance, seem to teach us nothing and can seem more white sound all around us that we chose to ignore. If we look at it more closely we find out that each advertisement is educating us on a product, convention, or idea that the makers want us to buy into or know about. Even texts written purely for entertainment can be used for educational purposes. Schools across the nation use classics like Huck Finn to teach students about aspects of writing and reading. A simple photograph can be used to educated the world on a situation, or in a photography class to show examples of concepts like contrast or focal point.
Clearly, all text can be used for educational purposes. Text is intentionally written for educational purposes. Even text that isn't intentionally written so can be used to educate someone. If we look deep enough, we can gain educational experience out of all text mediums.
