Why is "Kula ring" trending?

Wikipedia Overview

Kula, also known as the Kula exchange or Kula ring, is a ceremonial exchange system conducted in the Milne Bay Province of Papua New Guinea. The Kula ring was made famous by Bronisław Malinowski, who is considered as the father of modern anthropology, who used the test case to argue for the universality of rational decision-making and for the cultural nature of the object of their effort. His seminal work on the topic, Argonauts of the Western Pacific (1922), directly confronted the question, "Why would men risk life and limb to travel across huge expanses of dangerous ocean to give away what appear to be worthless trinkets?" Malinowski carefully traced the network of exchanges of bracelets and necklaces across the Trobriand Islands and established that they were part of a system of exchange and that the exchange system was clearly linked to political authority.
