@ _ID_ . . . i don't believe i implied books were useless, but why buy a book when one might not know if they are into that area per say. looking on the internet for better ideas, then going to books seems to me to save time and money.
If you want my opinion on best way to learn, it'd be going out to events and learning from people who know each area Or going to a "local" dungeon that offers "free" Classes. . . but in some cases that costs even more then books and not everyone is into being out in the public scene.
