The article appears to concentrate on nutrient value rather than flavor. You don't need to be a foodie to be able taste the difference side by side. In anything, it depends on what you're using a product for. For example, few people can tell the difference between real vanilla and artificial in many kinds of baked goods, but in ice cream the difference is more apparent.
Similarly, if you're making salad dressing with a whole lot of ingredients in it, it probably doesn't matter what kind of oil you use; canola will be fine. As reported in another thread, I found good, fruity olive oil in fact made less than stellar mayonnaise -- but if I'm making a simple vinaigrette, I want topnotch evoo.
With honey, it makes a lot of difference. Aside from the fact that different honeys taste different, much cheap honey is not, in fact, legally "honey." It's often ultra-filtered, which removes the pollen, making it impossible to trace its origins and eliminating some protein and trace elements, making it less nutritious. Such "honey" may be imported from China and can be tainted with illegal antibiotics and heavy metals.
Their mustard comparison is just silly. For some things you want yellow mustard and for others whole-grain Dijon. Yellow is what I want on a hot dog. It would not work in a recipe for mustard-glazed fish.
You need to evaluate what you're doing with the product and what it's most important characteristics are. The differences between prime and choice beef is apparent to most people in grilled steaks, but it's a waste of money to buy prime for pot roast. It is true that organic foods have no more nutrient value than non-organic; it's what else might be in non-organic foods that concern those people who pay the premium for organics.
