Jason Kottke imagined how the marketing meeting for Titanium cards went, but those “more precious than platinum” cards have been out for a few years now. And, not surprisingly, Citibank has already trumped Titanium with a new Diamond card. What’s next? As envisioned in this Atlantic commentary: “Ultimately there could be a Uranium card, with a debt load whose half-life is 700 million years.” I’m thinking that with the conflict diamond image problems, the next steps will be to run through the rest of the precious gems. You know I’d sign up for the Sapphire card.
