I watched a little bit of Notch's thing, it was fun. And for a more in depth topic, it could certainly be a great way to learn.
On the other hand I've come across 1-2 minute YouTube videos several times when googling how to use some specific API call, and I find it aggravating when all I really need is one little code snippet. I know how to type or copy 'n paste. I don't need to watch someone else do it. All I want most of the time is a well commented, nicely highlighted, code view on someone's blog (StackOverflow and github are just fine too!)
I can definitely see this as more of a 'watch me code something cool' idea rather than wanting to learn how to solve a specific problem. A lot of the benefit of being able to watch the streams is to see people get their questions answered during the cast, that relate to what the caster was broadcasting at the time.

Maybe I'm just old or old fashioned.
