Aaron (@aaronwall) says what he thinks, full stop, his insights into SEO have been extremely helpful to me over a number of years, and the tools he offers up are a great way to keep analytical data leashed to the post.  What i mean by that is that SEO book.com makes it unbelievably easy to tie down where your sites successes are, which direction you should be taking your SEM efforts and above all else a tongue lashing when you get it wrong, great website, great author a master in the making.
