Yeah I can see why a lot of people love it, but it's fundamentally anathema to the way I use docs. Considering how common other reference formats are, I can't imagine it's rare among developers, but I'm not sure. I'd love to do a usability study. Modern accessibility guidelines implore taking neurological differences into account with web content, but if it's not easily measurable or even a bit subjective, it's not going to get budgeted for in most cases. I imagine without expert advice, even gauging whether or not you've got the right approach is difficult.
