The NY Times is running a great piece titled "A Software Populist Who Doesn't Do Windows " detailing the vision behind the Ubuntu Linux OS and Canonical, the company behind Ubuntu.
Canonical, based in London, has more than 200 full-time employees, but its total work force stretches well beyond that, through an army of volunteers. The company paid for close to 60 volunteers to attend its developer event, considering them important contributors to the operating system. An additional 1,000 work on the Debian project and make their software available to Canonical, while 5,000 spread information about Ubuntu on the Internet. And 38,000 have signed up to translate the software into different languages.
Definitely worth a read.
