I have tasted these straws. I have seen children and adults alike flinch at these straws in disgust. Good luck to you. To me, they remind me of straw-shaped carbon filters in appearance, and taste like improperly mixed Quick in flavour.
Wombat, in regard to your "why do we need so many different varieties on the original" quandary, I think it was in Culture Jamming, where I read about the concept of how excess choice is actually only the "illusion of choice." Let's say all I really want is a bag of regular Oreos, and I go the the super-giant-mega-buy-anything-you-could-possibly-need-in-one-place store to buy Oreos, and I go to the cookie isle. There can quite possibly be an entire isle devoted to manufactured, packaged cookies now, nevermind the other area of the store with the bakery cookies, the refridgerated section with the cookie dough, the freezer section with frozen cookies and ice cream with cookies in it, the check outs with the individual serving sized packages... Anyway, I locate the cookie section where the Oreos are, and I discover the regular sized bags of Oreos (eye level) are surrounded by other Oreo products: Oreo cakesters, Chocolate Covered Oreos, Mint Oreos, Double Stuff Oreos, Reverse Oreos, Mini Oreos, 100 Calorie Packs Oreos, Lower fat Oreos, Oreos in large "family sized" packs, Oreos packaged in a way that's convenient for packing in school lunches, etc, etc. So instead of just going to an isle, and picking up a bag of Oreos, I am engaged in thinking about Oreos, excited by the possibility of Oreos, enticed by the thought of other ways of enjoying Oreos... and suddenly I've lost 10-15 minutes of my day to thinking about Oreos. Even if I leave with the one bag or Oreos I've intended to buy, I have been deeply engaged at the point of sale with the concept and possibility of Oreos. I have devoted more of my time than I would ever intentionally seek to spend on thinking about Oreos to doing just that. I have been mindfucked by Nabisco. Even if only 1 out of every 50 marketing ideas for Oreos actually succeeds, in the end getting consumers to think about, worry about, get confused about, excited about, talking about the product is an incredibly valuable thing.
Admit it, you all want an Oreo now. I do. Even after knowing TSP is in them. I even had a Cookies n' Cream Wagon Wheel last night and thought about Oreo Cakesters while I ate it. That's powerful marketing.
