Scales Vs Other measuring tools

Having just finished our latest cookbook I was struck by the words of wisdom from Gizmodo arguing that we should be using scales for ALL our measurements in our recipes. The argument goes something like this:

Recipes work better when you weigh ingredients. A cup of flour can weigh between 4 and 6 ounces. That means if you've got a bread or cake recipe that calls for 4 cups of flour, you might measure out 16 ounces or 24 ounces—a 50% difference in the main ingredient! . . . Measuring is easier and cleaner and results in fewer dirty measuring cups when you use a scale. You can measure everything right into your mixing bowl.
