Thanks to Hacker News I came across Write Your Damn Book. It takes an interesting approach to online courses by sending you the course content via email. I signed up and completed Lesson 1. So far I like the frank no-nonsense style. The questions posed were thought provoking and I answered them honestly after some self reflection.
I'm writing my responses to the lessons here in Ghost but keeping them private for now. If anything, I simply love the clean markdown driven interface. It allows me to apply minimal formatting to create a clean easy to read web page.
