Hi, I'm the author. I would like to add much more relevant content to the book, but I need to be realistic about how much time I can spare for this currently. We will see how it works out.
Maybe other people from HN can pick up the glove? Maybe a book deal with Manning/O'Reilly/Wrox (unless you're not interested in pursuing writing)?
I was just reading the Google+ public "How-to" collaborative doc the internet community has been building (http://bit.ly/qg0Yf6). Maybe the Node.js guide should take this format and make it into a living manual?
I think "Hands-on Node.js" by Pedro Teixeira is the perfect "next read" when you're finished with NodeBeginner. Pedro and I have bundled our eBooks at Leanbundle.com, maybe that's interesting for you: http://leanbundle.com/bundles/node
I just bought the LeanBundle - both your and Pedro's books look useful. I have played with NodeJS a bit and I am hoping that the two books get me to the point where I can do an "All Javascript" example app that functions like compiled GWT (Java to Javascript) web apps where the entire application lives in memory on the browser with occasional syncing between a server side data store and an in-memory data model.
