This incident has not been tested in court, but it highlights a potentially disturbing practice. In July 2016, German computer magazine LinuxUser reports that a German blogger Christoph Langner used two CC-BY licensed photographs from Berlin photographer Dennis Skley on his private blog . Langner duly mentioned the author and the license and added a link to the original. Langner was later contacted by the Verband zum Schutz geistigen Eigentums im Internet (VGSE) (Association for the Protection of Intellectual Property in the Internet) with a demand for €2300 for failing to provide the full name of the work, the full name of the author, the license text, and a source link, as is apparently required by the fine print in the license. Of this sum, €40 goes to the photographer and remainder is retained by VGSE.  
But the key challenge facing the commons today isn’t quantity – it’s usability, vibrancy, and collaboration. Today’s web is social and interconnected, and it has completely changed the way we share, tell stories, and build communities. While integral to many kinds of creativity and sharing, Creative Commons has yet to fully activate the content and creators in our movement. We need our contributors to be able to talk to each other, find new content, give feedback, offer gratitude, get analytics, and build networks around the content they are creating. We need to light up the global commons.
