If I ever chatted with you about developer experience in person, I’ve probably drawn the developer funnel for you on the whiteboard. For some reason, I always draw it as a funnel — but any power-law visualization can suffice. As an aside, I do miss the whiteboards.
This funnel can be a helpful framing for a conversation about desired qualities of the API. Do we want to have rapid growth? Probably want to be aiming somewhere higher in the funnel, designing convenient, harder to mess up APIs. Want to introduce powerful APIs and not worry about the sharper edges? Expect only a small number of consumers who will understand how to use them effectively.
