I saw the title and clicked without knowing the subject matter. I'm not a breeder and don't plan to ever be one, and still found it interesting to read. Some that breed don't want to further their knowledge - unfortunately.
I do have an interest in someday possibly showing dogs and currently love attending shows. And, anything I learn about the subject of breeding would only help in my enjoyment of shows, even if only as a sidelines viewer and lover of this breed. I believe it helps to understand what you are looking for in the ring.
