Nick writes such good articles the only thing that's better are his live lessons. My favorites by far are the survival guides and tutorials that have thought me so many new skills and my kid looks at me like I am a superhero!
Tip for consumers: If you are truly interested in learning, take up any of the articles in the tutorials or skills sections. The posts are short but have enough info to get you started on the topic, or to know exactly how to execute whats covered in them.
