There really isn't any technical details about this at all from what I read in the article or using the interactive tool. If this is a SaaS product for developers, wouldn't the actual "deep dive" I expected contain that? It's to high level and doesn't offer more value than some general blog telling me a few basics w/ some links to better content. Did I miss something? I think the interactive tool is a cool idea none the less.
