Charging its most avid readers for digital access was officially not a dumb idea for The New York Times. In its second quarter earnings announcement, the Times Co. included some attention-getting figures for its new digital subscription program, which launched in March. Since then, the paper has amassed some 224,000 digital-only subscribers. Another 57,000 subscribe to replica editions delivered on e-readers like the Kindle and the Nook. On top of that, there are the 100,000 people getting e-subscriptions sponsored by Lincoln.
