The book starts by offering a simple categorization, that helps the reader find his way through the 57 different sources. Some of these can prove extremely useful (such as Flickr and Delicious), while the author is honest in mentioning specific drawbacks that some of the sources have. The links in the book are also a welcome addition (although I don’t really know if it could work well in any other way).
However, this book is definitely not for people with no programming skills. In my case (I have limited programming skills) it was a bit hard to get used to the book. Adding to this, the main drawback of this book is that it’s short, but this is normal, as it is not meant to include full descriptions.
Overall, this is a great toolbox for developers wishing to enhance their services. I enjoyed experimenting while reading the book (and learning as well, in order to improve my programming skills) and I’ll definitely keep on searching for related titles.
