OpenSocial is not really simple, even somewhat confusing due to its technology heritage as it kind of got re-purposed from gadgets API to play catch-up with other social application containers. For that reason any book on the subject is welcome. Although to be fair there are only few examples in the book and even less working ones, it took significant changes to get most of the code examples running on just one of the many available OpenSocial containers. If you want to write apps that do more than sending a HelloWorld to a friend you are probably interested in the REST API and server side code with a DB. Unfortunately not much is covered in this book on that subject. It feels like the authors have rushed to get the book out to be the first ones to cover the OpenSocial techno. Don't count on updates of the code from the site, I have downloaded it a few times just to see if they would updated the files. The answer is no, it still has all the same many syntax errors as the printed code. I am clearly disappointed by the book compared to other API related books but at the time of this review it is the only one available on the topic so for that reason I still gave it 2 stars!## Summary: ## Too Many Words, Not Enough Code, Too Many Errors... but 1st Book Available on OpenSocial to be fair...
