Gabriel Tarde's near-contemporary, the sociologist Georg Simmel, noticed something peculiar about fashion in 1904: it moves in two directions simultaneously — upward imitation and downward distinction. The moment a style reaches the masses, the elite abandon it. Simmel called this the 'tragedy of culture,' but what he was actually describing is a structural law of markets. Every product category follows this cycle, and most businesses only see one half of it. They track adoption but miss the defection signal — the quiet moment when the early adopters who validated your product start looking for the exit. In business, the peak of your metrics is often the peak of your relevance, not proof of it. The concrete move: map not just who is joining your product or market, but who among your earliest and most vocal adopters has quietly gone silent. That silence is the leading indicator your dashboard isn't showing you.

Name one specific customer segment or user type that was loud about your product 18 months ago and is now silent. What does their silence mean?
