The title is just a statement of how long it took to sell out, "WWDC sold out in ten hours." — tell me where the exaggeration is in that sentence.
In 2009 Google I/O was sold out only after ninety days and Apple’s WWDC was sold out only after more than thirty days. In 2010 both conferences sold out only after a few days.
That both conferences now sell out in substantially less than a day is newsworthy and a grand feat.
