I'm also interested into more of these "teach yourself x" curriculums if anyone has anymore to share. There's so many things I want to learn and I'm someone who likes (needs?) structure. Here's a few that I know of.
"How to make great pancakes" sadly is not one of the anything to be learned.
From poking around, this site seems to be a pointer-to-resources, rather than a road map of learning. While very useful, it seems like a tactical resource, rather than GPs strategic resources.
