Not really appropos to the article, but in reading kid's lit to my girls, I note an inverse correlation between the quality of a kid's book and the authors reliance on using the word, "exclaimed," which is a word that seems to only exist in kids' books.
Dr. Seuss can get through great stories without anybody ever exclaiming anything. So can Sandra Boynton. (They're also writing in verse.)
But those soft-cover books about TV characters on the wire racks in the book store? Dora's always exlaiming something. As do, sadly, then Berenstein Bears. And so on...
