I interpret "stuff you know" as easily-recallable facts. Obviously at the highest level view knowledge is what separates a beginner from an expert. Knowledge is much more than "stuff you know", though. It is about understanding why, knowing how to handle non-textbook situations, and knowing where to find the facts you need when you need them.
