What Would be Your Choice of Material to Learn?

Over the coming months I’m going to dive in and create more and more course material with screencasts and more. I’d like to get an idea for the demand out there among you, the kick ass coding readers of my blog. Care to throw down a vote? Spread the word, pass it around, email, tweet & facebook it too! Would love to get a wide slice of poll answers & feel free to throw a comment or two into the fray too!
