One key to keeping software projects and the surrounding communities healthy is keeping friction for all audiences to a minimum.
In MyBB, this friction is derivative of user experience and developer experience. Our largest audience is formed by the end users - people browsing online forums, not expected to know what MyBB is, yet benefitting from fine-tuned visuals, phrases, and flows that come out-of-the-box. At the same time, we target two groups further down the forum assembly line, for whom both UX and DX apply.
