Hey Aparsons, thanks for your feedback. As mentioned in the post, the Handbook is not finished and we'll continue to evolve, adding more chapters, meat to the current chapters, and we have other ideas like exercises.

It's good that you are interested in Scaling WebSockets, because that is the chapter I am writing now! I hope to get it live in a couple of weeks, once it is I can send you the new version.
