National Ambassador for Young People's Literature

In a post this past weekend, Roger Sutton talks about selecting the new National Ambassador for Young People's Literature. Currently, it's John Scieszka. Roger's post has a ton of comments with suggestions for the new ambassador (any suggestions, Misfits?), but one asks a great question, which is what exactly did Scieszka DO in this post this past year? I know what he hoped to do and achieve--he lists these goals on the website linked above--but I'm wondering what he really did as an advocate for children's literature and the importance of reading. Anyone know?
