Learning Vim From the Inside

Vim improves on vi in countless ways.  As a curious vi expert, I wanted to know exactly what those were, so I dove into the source code.  In doing so, I was compelled to create this online class a few years back: http://curiousreef.com/class/learning-vim-from-the-inside/

It's still going strong.  New students join every month.  For the most part, it runs itself now... but if you hit any hurdles while working your way through the content, please reach out to me and let me know.
