An update:
Our 2nd annual Wiki-Conference NYC will be held over the weekend of August 28-29 2010, hosted by ITP at NYU's Tisch School of the Arts, and also supported by Free Culture @ NYU and Wikimedia New York City.
Wikimedia Foundation Executive Director Sue Gardner will be giving a keynote, and we will also have a second keynote speaker TBA.
There's still plenty of time to join a panel, or to propose a lightning talk or an open space session.
