I have only read the first two chapters (setup and Javascript an overview).

The content do not look bad (but I have not read node.js specific parts yet so I can't really tell). The bad part is that it would need some serious proof-reading... Some sentences are missing words or are hardly understandable and there are some mistakes in the code.

Reiterating the sentiment. Seems great so far, but there are some errors that could create confusion. The good news is the author left his email address, so I dare say he's well aware by now :)
