Jamie Love has been extolling the virtues of Ubuntu in particular and free software in general over at the Huufington Post.
"In general however, it will be important for individuals to switch to Linux, not only from Microsoft, but also from Apple. Today many free software proponents don't use free software themselves. Because of this, they often don't fully understand or appreciate the ways the platform works, the policies (by individuals, organizations, regulators or governments) that would make it work better, or the interesting ways that innovation is created and managed in an environment where knowledge becomes community property. I'd like to use analogies to better explain the difference between talking about free software and using free software, and I'm sure there are plenty -- is reading about sex the same as having sex? Can you really understand foreign policy without visiting foreign countries?
Because of the stakes, people should increasingly be thinking of free software as a social movement. It is not only about a small number of programmers and engineers. It is about everyone who cares about the future of knowledge ecosystems."
