Points, badges, and leaderboards are the first thing every app reaches for, and also the most documented failure in product history. LinkedIn retired its top-voice badges, Foursquare scrapped mayorships, and Google News killed its badge system for the same reason: they motivated activity without meaningful behavior. Yu-kai Chou's framing is the cleanest: PBL is the scoreboard of a game, not the game itself. Most apps build the scoreboard and forget to build the game.
