I completely agree that the article did little or nothing to help the parents of gifted kids, which is a shame since this is going to add up to a lot of kids.
That being said, when I read the Parenting article, I remember liking how it normalized "normal." I felt at the time that its goal was not to dismiss giftedness (it did dismiss it, but that wasn't its point), but to help parents of ND kids to appreciate the value in their children and not to force them to be something they are not. I really liked that.
