As I was getting to the end of writing this book (mid-2008), Facebook announced that they were planning a major redesign of their Profiles and the way that applications integrate with them. That decision sure made for exciting times in these parts!
Luckily, the timing worked out nearly perfectly, and this book now contains information about the “Profile redesign” rather than the old way of doing things. The new design was still in the initial phases of being rolled out as we were wrapping up the manuscript, so some of the screenshots still show the old design we knew and loved, rather than the new design we’re fumbling around with but are pretty sure is going to become our number-one squeeze. Fear not: the screenshots were updated anywhere that it was absolutely required. It’s also possible that some of the information changed after we went to press, so check the Developers Wiki if you think that might be the case (http://wiki.developers.facebook.com/).
It’s also worth noting that some of the applications profiled in this book are no longer, and that some have completely changed their look, feel, and very purpose in life. Scrabulous, for example, is consistently used throughout as a paragon of what to do right, but it has actually fallen prey to its legal battles and has been reborn, phoenix-like, as Wordscraper (http://apps.facebook.com/wordscraper).
