If you want to fling ideas back and forth on the Greek yogurt thing, I'm reasonably certain I'd be able to expound upon the article you linked to (what consumers are looking for, role of product in that, relative importance of price, etc) (thank you, Marketing).
Also - I didn't know that you, too, are anti-Halloween! I tried to play along for a number of years (college) and have recently rebelled ("I won't come to your party if I have to wear a costume"). I don't like dressing up in costumes. I'd always rather be myself. Halloween last year was maybe the best ever - D and I hid out in his house and watched Japanese movies, just the two of us, no costumes. I do love handing out candy to trick-or-treaters, though.
