This piece is based on posts made in the United States during the evening of February 26, 2015. All data has been anonymized and aggregated. Last night saw one of those beautiful moments made possible by the interconnected age we live in: someone posted a picture of a dress, and the Internet lost its collective mind. Was the dress black and blue, or was it white and gold? The furor even drowned out what would ordinarily be a strong viral winner of the day, a video about two llamas on the lam.
