eldavojohn writes "As a web developer in the 'Agile' era, I find myself making (or recognizing) more and more important decisions being made in developing for the web. Scalability Rules cemented and codified a lot of things I had suspected or picked up from blogs but failed to give much more thought to and had difficulty defending as a member of a team. A simple example is that I knew state is bad if unneeded but I couldn't quite define why. Scalability Rules provided this confidence as each of the fifty rules is broken down in a chapter that is divided into what, when, how, why and key takeaways. A strength of the book is that these rules cover all aspects of web development; but that became a double edged sword as I struggled through some rules meant for managers or technical operators."
