I already posted to the original but thought I would chime in. I like the idea of guiding someone through some code with a narrative. Your tool is very helpful for this.

I have a similar tool but it allows the comments to be added to the code as it evolves:

The main difference being that the context of the comment is always in line with code at the point the comment is made. One other difference is that a person can add drawings and audio to their comments.
