I agree that it would have been nicer to see that issue addressed head-on. I think Karim is conflating the words unscripted and unprepared.

From what I understand, Khan keeps the videos unscripted so he can maintain more of a conversational style, but he's always careful to understand the material very well before doing a video on a subject.

My lad (now 7) has done some of the maths problems and we've used the videos to provide the background to attempting those problems. IMO from the half-dozen videos I've seen they were both 'unprepared' and unscripted - but that might not be bad. They're the sort of thing I think one would come up with if someone puts you on the spot and says "teach me how subtract". Obviously these are low level maths subjects. He's not unprepared in being able to do this sort of basic stuff but I think a little more polish would make such videos a lot better.

One thing I found quite frustrating was the lack of technology applied to making the video - in the few I've seen he takes ages drawing out number lines (for example) and the writing is quite unclear; it doesn't appear to be too hard to have a marked axis that you can paste in when it's needed. Petty issue but something I didn't expect to find on this much touted resource. Another example would be hand drawing bunches of marbles/tins http://www.youtube.com/watch?feature=player_embedded&v=D...; I guess it naturally limits the pace, which may be good.
