Originally I was going to comment that there's no need for a blog when you've got this nice notebook format, but having clicked your link I can see why you have both -- it takes forever to load the notebook. Are you hoping to get that load time down in the future? It would be nice to do away with the markdown blog entirely.
Love this and as a fellow GIS software traveler I’ll share optional guidance that ESRI has trademarked that term for a very similar product. Might be worth thinking about alternative naming ideas.
