To my friends and colleagues at Clearleft: Thanks for providing encouragement and feedback throughout the book-writing process. And especially to Natalie Downe for lending your experience and breadth of knowledge to this book: Your support and guidance was invaluable, and I still don't know where you manage to find the time.

To all my colleagues who continue to share their wealth of knowledge in order to make the Web a better place: This book would not have been possible without the previous work of the following people, to name but a few: Cameron Adams, John Allsopp, Rachel Andrew, Nathan Barley, Holly Bergevin, Mark Boulton, Douglas Bowman, The BritPack, Dan Cederholm, Tantek Çelik, Joe Clark, Andy Clarke, Simon Collison, Mike Davidson, Garrett Dimon, Derek Featherstone, Nick Fink, Patrick Griffiths, Jon Hicks, Molly E.

Andy Budd

First, thanks to you for choosing this book. I hope it improves the caliber of work you do, day in and day out. I'm endlessly inspired by the potential of those in our industry, and that includes you.

I echo Andy's words in giving thanks to the many notable individuals that have shaped and refined the Web, making it a better place today than it's ever been. Years from now, these individuals will be just as revered as those men and women who first sent men to the Moon.

A special thanks to Aaron Barker (aaronbarker.net) who assisted with several of the jQuery and AJAX examples in my case study.

Most importantly, I give my utmost gratitude to my beautiful wife, Suzanne, and four sons, Everest, Edison, Isaac, and Hudson. Without their love, support and patience, the work I've produced to date would not have been realized.

Cameron Moll

I must thank my friend and colleague Gregory Wood for his ideas and assistance with the "Climb the Mountains" concept. Everything he produces inspires me, and he's the designer I want to be when I grow up. I'd also like to thank all of my colleagues at Erskine Design for their support and for turning a blind eye to my feverish work on projects such as this. Big thanks to Simon Campbell, Jamie Pittock, Glen Swinfield, Phil Swan, Vicky Twycross, and Angela Campbell.

Above all, I should take this opportunity to thank my mum, and those that I have lost since the first edition of this book, my two grandfathers, and especially my dad. I still do this stuff to make you proud, even though you've gone.
