OK people, we did it, Museum Selfie Day has once again come and gone, and what a day it was. It’s just the second year of the semi-official but fully sanctioned celebration of every egoist’s favorite iPhone trick, taken in temples of art. And a year after it was invented by museum folks Culture Themes and Mar Dixon, we now have an opportunity for every art institution to drum up free advertising via social media by encouraging the sharing masses to post #MuseumSelfies on feeds so they can go forth and get viral and turn into ticket fees. And boy, did it work.
