I don't know too much about this morning's children's book award winners--the Newbery winners, especially. Never heard of 'em. I do know that Laura Amy Schlitz, winner of the Newbery, also wrote The Drowned Maiden's Hair, which was one of my favorite books of 2007, so I hope her award pumps up recognition for that book as well.
RE: The Invention of Hugo Cabret taking the Caldecott: loved the book, but am unsure how I feel about a novel winning a picture book award, no matter how many illustrations.
RE: The White Darkness winning the Printz: YES! This book was fabulous--read it. It's a thriller / psychological study / all around gripping story of a half-deaf girl adrift with her insane uncle in the Antarctic. That description isn't doing half as much justice as the book deserves. Go buy it.
In my actual life: I moved this weekend, update to come.
