There seems to be a trend of coding screencasts popping up online and I think its great. You learn coding best by doing and watching a screencast, actually seeing how the experts create and craft software is way more engaging and informative than reading it off a book. You can actually hear them talk about design choices and tradeoffs, see how they use IDE's/text editors and pick up a lot of best practices in general.
I think its a great alternative (as opposed to long/messy consulting gigs) for startups with solid technical talent to generate a stream of revenue and bootstrap to success.
