Edit: downvoters, thanks! I realize this is not an easily agreeable opinion ("let's all chant 'death to YAML!'") but it's really easy to avoid losing money on something like this. Just do proper testing. Aren't you setting yourself up for surprises if you write file formats such as TOML and YAML without reading the documentation, learning and experimenting first? How about unit testing? Or verifying the type in your config parser? Have you tried opening your site in the norway config on your development or testing environment? Or even in production? It all seems very basic and not at all blog post or even HN worthy. I'm going to assume the authors still haven't learned their lesson and are going to experience many more surprises in the future working with plain text file formats.
