Simon Kloostra, the author of Joomla! 3 SEO and Performance, joined us virtually from The Netherlands, which is why we adjusted the time due to the 6-hour time difference.

He did a great job on this book, which provides information every Joomla! website developer should know but is difficult to find in one place.  

Our review on Amazon.com is pasted below:

Joomla SEO Performance KloostraSimon Kloostra’s book, Joomla! 3 SEO and Performance, is a very focused, short book that is chock full of useful tips and links to resources that Joomla! website developers and administrators may not be aware of. As a long-time Joomla! user and founding member of the Northern Virginia Joomla! Users Group, I find that this book fills a gap on my Joomla! bookshelf.
Simon Kloostra (see his site at joomlaseo.com) is clearly an authority on Joomla! and SEO, but he avoids unnecessary jargon, provides context, and explains SEO in a clear and pleasant style. As of the date of this review, the book is quite current. It includes evaluations of and recommendations for dozens of resources to consider for your toolkit.
One frequent question in user group meetings is which commercial template provider is best. This book does get specific and list well-regarded template providers, and also delves into the SEO considerations of template design. This which gives the site developers something more to consider in making their template selection or development decisions.
Perhaps even more valuable is his coverage of ways to maximize Joomla! performance. We have all seen sites that are slower than they need to be; this book explains what to do about it and provides a clear explanation of caching options and ways to optimize both css and javascript files.
Even those with good backgrounds in SEO and Joomla! will find additional insights that will justify their investment in buying and reading this book.
