A bottom-up, building blocks approach to interoperability makes the barrier to entry small and the value large, as opposed to a monolithic all-or-nothing protocol approach, which demands compliance due to its implementation’s incapability of gracefully handling partial support.

Building blocks give creators freedom to implement what’s important to them in the order it makes most sense, getting positive feedback from low hanging fruit and making complex tasks managable.

Stop designing protocols. Create building blocks.
