Where are the Book Reviews?

Jane Ciabattari, president of the National Book Critics Circle from 2008 to 2011, has put together a great overview of the current state of book reviewing. She includes links to lots of different book review sources and a summary of where each one is coming from editorially.  In reading this article I discovered that Sara Nelson, former PW editor, is now Book Editor at O. This is probably old news, but I hadn't heard where she had landed.
