The Open Everything conference is happening in New York City at the UNICEF headquarters on April 18. Their mission statement:"Open Everything is a global conversation about the art, science and spirit of ‘open'. It gathers people using openness to create and improve software, education, media, philanthropy, architecture, neighbourhoods, workplaces and the society we live in: everything. It's about thinking, doing and being open."This year's event features speakers from Google and Open Source Intelligence as well as a number of audience-driven sessions. And registration is still open! There's more info on the Open Everything site here.
