Love this article. It makes statistics enjoyable and accessible. Most of Olah's old stuff is also really good, especially the one on manifolds and neural networks [1]
You might like to check distill [1], it's a journal with a limited amount of content for now, but of very high quality, and C. Olah is one of the editor.
