Great question.
Wikipedia is an interesting case study. It worked well in the past, but I would argue that it now suffers (and has for some years) what Warren Buffet called "the institutional imperative."
It used to be a very lean organization, and now is anything but. There are some interesting answers as to the why of this bloat. But many people agree that—again, for some years now—Wikipedia has cancer.
Personally, I would love to see a move away from "Siren Servers," towards something that rewards people monetarily, i.e. something along the lines of programmatic V4V splits. I believe it would solve some of these problems, but it probably will also introduce new problems. That's just how these things go.
In any case, I'm so bullish on V4V on Lightning in particular because of its directness and transparency, which should—at least in theory—reduce administrative and other bloat.
