One drawback of being a global megabrand like McDonald's is that it's hard to get people excited about you. Consistency, it seems, breeds stagnation over time. That's why there's so much social-media focus on the McRib this time around—it stimulates conversation, so why not make that process easier for consumers? Whether or not they buy, or even like, the sandwich is irrelevant; it's less expensive than creating a new menu item, and it keeps McDonald's fresh in the minds of people who've already decided to eat out. The beauty of the McRib is that, whether people love it or think it's gross (and that's a fairly even split), it gets them talking. Plus, the McRib hasn't been on the menu since 1994, so there's an entire generation of fast-food junkies who've never had one, and some of them probably haven't even heard of it. Now, maybe if we eat enough McRibs, they'll bring back the Arch Deluxe.
