This needs some videos to show what it can do. Not many teachers know what GitHub is and if I wanted to suggest this as a possible option I could not explain it to them.

Maybe a video showing the creation of an assignment and sending it out (url via email, is it?), students completing the assignment, and teachers looking over a completed assignment.

If that is a poor example of what this does then I missed the point entirely.

That's rather unfortunate, as more and more of the people putting their degree to work definitely need to know what it is, especially in start ups.

My university showed us 'RCS'...

Thanks for the suggestion, we're working on more and better documentation for teachers.
