We were excited to have Lawrence Lessig join us as a keynote speaker at the Historypin launch event at the Museum of the City of New York July 11, 2011. He explored ideas of cultural heritage combining with the open architecture of the World Wide Web, as well as the challenges of legal frameworks that have not been designed with that same openness in mind. It lead to an evening of inspired conversations with institutions and individuals investigating new ways to share and explore cultural heritage on the web.
