I'm the author of The Node Beginner Book. Thanks for discussing it here.
Your input is a great help. I see the points WA makes regarding the bad things.
It's true that it's yet another Node tutorial chewing around on the web server / web app stuff; but I think for the people I'm addressing it's still the most useful scenario because it allows to understand how a full fledged app is put together, and is a great example to explain all of the fundamental concepts, new JavaScript ones and conventional ones (because it might makes sense to understand what stuff is done differently and what is done in a known fashion).
So nothing really new here - I hope where this tutorial differs is that it (arguably) might be the first "one-stop" tutorial for Node to get beginners started. Not more not less.
Every other resource I could find forced me to google around to fill the gaps - while this is not a bad thing per se, I think sometimes it's nice to have something that really guides you from A to Z.
Like, for example, http://ruby.railstutorial.org/. If I manage to create something that's only 10% as cool, I'm going to be very happy :-)
