The difference between a living surface and a dying product comes down to how growth happens. A product accumulates features through a roadmap — a roadmap is a commitment, a coordination problem, and a tax on every change. A card grows by slots, each added when it earns its place and cut when it stops getting read. The card's extendability is the contract: adding is cheap enough that the question becomes 'is this interesting?' instead of 'is this a two-week project?'
