I am Ton Roosendaal, chairman Blender Foundation. AMA!
My short bio: I am Ton Roosendaal, the original maker of the open-source 3D creation suite Blender, and the producer of the well known short films Big Buck Bunny and Sintel. Currently I'm working on Project Gooseberry, which brings together 12 independent studios from all over the world, who will work with open source software, in an open production environment, to deliver an open content feature animation movie. We're currently crowdfunding this project here: http://cloud.blender.org/gooseberry/
