Michael,

I've been working through the HTML version; great job! I especially appreciate the coverage of Ruby Version Manager, git (topic branches, merging), Heroku deployment via git, and TDD via rspec. You can read all about something, but it doesn't really sink in until you've typed the commands yourself -- even if those commands are dictated word-for-word by a tutorial. I generally dislike video tutorials, but will take a look at yours.
