This is the best way to pick up the fundamentals of a language, but definitely not appropriate for learning deeper concepts. You can only learn what's new. If you're driving yourself, "new" can only be stumbled upon, which is extremely inefficient. It's much better to find somewhere with a consistent presentation of "new", like a book, or complex source, written by people that regularly use the "new".
