Doug Hull, Tom Lane, Gerard Torenvliet, Alex Conn, Amy Groden-Morrison, Susan Fowler, and Robert Nero all supplied material and links that I've included as key examplesthank you all for those screenshots and suggestions, and I hope the text does them credit.

At O'Reilly, thanks to Nat Torkington, who "found" the original web site and contacted me; Mike Hendrickson, for guiding me through the early stages of the book and coming up with some terrific ideas for it; and Andrew Odewahn and Mary O'Brien, my helpful and kind editors during the later stages of writing the draft.

The thousands of anonymous visitors to my UI patterns web site are the reason why this book exists. Without your log records, I'd never have known how heavily used the site actually is. And thanks to those of you who took the time to write and tell me you liked it. I hope this book meets your expectations!

Many, many thanks to my family and friends, especially Rich. You all encouraged me to turn the web site into a book, and supported me wholeheartedly throughout the writing process.

Finally, I want to thank our local champions: the 2003 and 2004 New England Patriots and the 2004 Boston Red Sox. You all helped us believe that anythinganything!can be possible if we try hard enough.

Even writing a book.
