«For years, Flickr has been one of the most important repositories of Creative Commons imagery in the world; now, thanks to a new design, it's all but useless for serving and attributing the CC-licensed images it's been entrusted with by museums, galleries, national archives, libraries, and millions of individuals.» http://boingboing.net/2014/04/07/restoring-cc-attribution-to-fl.html
Didn't pass here yet I think, though many commoners care a lot about this sad fate of Flickr for obvious reasons including the ease with which stuff à la https://commons.wikimedia.org/wiki/Commons:Flickr_files/Appeal_for_license_change earns us new material daily.
