The corollary to all this. Companies with open source strategies should really consider hiring and retaining good writers alongside the core developers. This is the reason everyone thinks Dan Abramov created React, he is simply the best communicator when it comes to explaining the mental models around React development. You might have amazing technology, but if you have no one advocating it in a beautiful and powerful way, it won't matter for adoption. React is at a precipice for sure, and there are a bunch of great writers on that team, but there have been a lot of good ones that left recently as well, and that's something Facebook should strongly address.
