I feel a bit churlish, but this kind of thing always leaves me nonplussed. jQuery and Javascript have excellent references, and I have a hard time understanding how anyone really learns any technical topic without working with the technology and exploring the reference.<p>I know this is my own auto-didactic prejudice, but I see a lot of this screencast stuff and am set back by how much people seem to want to be spoon-fed skills, and by my own disbelief that skill can be acquired that way.
