Samuel Klein has spent many years developing collaborative communities. He is an advocate for free universal access to knowledge and tools, and a veteran Wikipedian, founding the project's first newsletter and translator network, and organizing last year's international Wikimedia conference in Cambridge.
Previously he has worked to develop software and supporting communities for machine-assisted human translation, and to set up free education centers. Klein is interested in local and sustainable knowledge development, and structures and principles that help this flourish. He establishes ties with teachers, game developers, and publishers, helping them to understand the need and uses for free and open materials, and to work with the global community around open education.
