I think there still was one good point in the parent comment that you did not address. If screencast were not the reason of RoR popularity but it's consequence, then maybe we should not lose too much time on making screencasts and instead concentrate on some other things? I have to attest that screencasting does require enormous amounts of time, especially if you try to do that on Linux where the tools break every 5 minutes and you need to make manual savepoints to keep with moving ahead with your work. Even though it was also very captivating and quite entertaining.
