The Free Software Foundation will be hosting it's annual conference, LibrePlanet, this year in Cambridge, Massachusetts on the weekend of March 22 & 23.
The LibrePlanet wiki describes the conference:
The mission of LibrePlanet is to empower a global network of local and academic groups, project teams, interest-based work-groups, and individuals all working together to advance free software and free culture as a movement for social justice.
As media and technology mediates how we experience and interact with the world, the private owners of software, knowledge, and culture have control over us. With a strong commitment to free software and free cultural works, we work against the exploitation, domination, and oppression enabled by private ownership of technology, media, and communication. While free software and free culture are radical stances against one form of oppression, we acknowledge that there are systemic structures of control embedded in our society which permeate our movement. Therefore, we maintain a Code of Conduct which takes those into account.
Our vision is to free the world from technological and legal barriers for all software and cultural works to be free as defined by the GNU Project and Definition of Free Cultural Works.
Unite: Bridge connections between hackers, activists, and participants in the free software and free culture movement.
Educate: Produce and distribute informational resources on free software and free culture.
Empower: Provide support and guidance for people using and contributing to free software.
Connect: Form alliances with related organizations and build coalitions with other groups working against oppression.
