OK, _why is amazing, but the Poignant Guide is really not the best place to learn Ruby. It may be for some, but I have to be honest, it diverges so much into madness and a pointless, meandering storyline for so long that I couldn't bring myself to finish it. I've spoken to others with the same experience. Maybe the first few chapters are worth reading, if only to get references like "chunky bacon". I suggest the pick-axe book for some good Ruby learning.
