I love this idea. It's like crowd-sourcing code comments! That has tremendous education potential, especially for people like me who learned by looking at other people's code, copying & pasting it, then tweaking it. And the beauty here is having people other than the original programmer add comments. There are a lot of open source projects on which I'd love to see this. There are lots of ways to extend this concept too. I echo what joeconway wrote - having a way to filter and view the comments in a tutorial-like fashion would be great. Having a way to somehow submit patches and fixes back to the original source could be cool too. And offering this as a tool for computer science professors, programming instructors, and other educators (e.g. giving the comments in their example code a nice UI, almost like a documentation generator) could be interesting. FYI, I just noticed the other tool, Noted Code, in the comments here. I prefer how Noted Code puts the comments and code side-by-side. Perhaps there could be a toggle for both views. Just some random thoughts. Keep up the good work!
