Are such stats (readily) available? As the inventory in the app store ages, I hope Apple applies adjustments to its rankings to identify "zombie" apps, those that perhaps had their day but have grown long in the tooth. I'm not suggesting that an app isn't a good if it hasn't been updated in a while—I still love IA Writer despite it not having been updated in nine months(?)—but increasing app counts make for a looming merchandising nightmare, and Apple (and other app store runners, such as Google, who will have more apps on its hands come 9:02am on August 19th, 2011 according to a market research firm) is going to need to incorporate more signals in its app ranking, selection, and automated merchandising systems.
