Le lundi 26 novembre 2007, M. Douglas Vos, fondateur de la page Facebook Designing With Web Standards:
Monday, November 26, 2007 is the day thousands of Standardistas (people who support web standards) will wear a Blue Beanie to show their support for accessible, semantic web content. … Don a Blue Beanie and snap a photo. Then on November 26, switch your profile picture in Facebook and post your photo to the Blue Beanie Day group at Flickr.
