Comment: I agree with BayShrimp the sources are enough to meet  for a short article on the topic. It's a mechanism of consensus decision-making, as one source says other countries accomplish the same thing through raising hands higher, same idea. Ideally we'd have an article on this model in general before splitting off named variations used by OWS, but until then why not keep this content as it meets GNG. If it disappears in 5 years as a failed experiment and no new sources it can be revisited or merged to OWS, right now hard to tell
Stance: keep
