Well, maybe if it does indeed hit Mars and we can get good pics of the aftermath, the general public might believe the scientists currently mocked as Chicken Littles that such an impact could happen on Earth, as it has in the past, and get people actually doing something about a planetary defense against this potential cataclysm! Or people would see the pics, say, "way kewl," and keep on updating their MySpace pages with pics of their pets.
