Yule in Denmark

December 28, 2013 by


In my previous blog I speculated that the Danes use ritualistic feasting as a way of creating a shared sense of belonging, which is an important basis for social cooperation and trust. Last week I was able to make more detailed observations on one such collective ritual. During the period preceding Christmas there are a […]

Thou Shalt Tweet

March 6, 2013 by


I have been vaguely aware that a social networking service, called Twitter, has been gaining in popularity over the last few years, but I did not pay much attention to it.
