Coca Cola turned in lackluster earnings for the latest quarter. I don't have all of the answers to their problems, but I know one thing they could do. Diet Coke tastes like shit. This is a deliberate strategy as Coke has been terrified it might sell better than regular Coke, so they formulated it to taste inferior to regular Coke. Well, people would buy more of it, perhaps lots more, if it actually tasted good. I doubt they'll follow this advice, but they should.
