Hmm.. Yes you might be right that lukeprog could do better. He's already clearer, though less engaging for a popular audience. But I don't think necessarily that learning the tricks that are so obvious in Gilbert precludes him from doing better. As my guitar teacher used to say: "you have to learn the theory, drive the theory into your head, and then forget it when the time comes to really play". Also, it might be perfect for the rest of us mere mortals.
