I was on reddit back in November reading a discussion about learning javascript and jquery. The New Boston was brought up as a resource for learning and a whole bunch of people started bashing TNB and other video learning resources saying it was the worst way to learn. They said if you are serious about learning a programming language you need to at least invest in a good book on the subject. So as an experiment I started reading a book about javascript. I can tell you that I got way more out of the TNB tutorials than I did out of that book.
