BIL started as an unaffiliated unconference satellite to TED’s structured ‘invite only’ paid conference. BIL is an open, self-organizing, emergent arts, science, society, and technology conference. Anyone can come, and anyone is able to sign-up to speak, limited only by space and time.The unconference structure allows for egalitarian treatment of anyone in any role; everyone is encouraged to participate where they can, whether that's clean up, set up, getting coffee, listening, AV work, blogging the conference, registration, etc.
