I agree, this functionality is not required to make the product succeed. The product is already useful in itself.

I was merely referring to a use case of someone learning to program / think like a programmer by watching replays of real programmers doing their job. e.g. similar to pair programming / training with a mentor, but be distributional across the internet.

As far as 'training' / 'learning':

- If the student looks at some finished code, they can understand how to do something for a specific use case once, but maybe not know how the original programmer got to that solution.

- If the student watches someone write that code, they can understand how to write something similar again themselves and know roughly the process of thought that was used.

- If however, the student can not only watch someone write that code, but also 'understand' why they wrote certain code in places or why they changed the code throughout the process, then they will not only learn how to write for this particular use case, but become a more competent programmer and be able to apply what they learnt to many situations, in context of what is required.

that's what screencasts are for - write code and annotate it with with a voiceover as you along. There is big enough niche between plain text code and screencasts.
