Bradley Kuhn is not a lawyer, but he works at the Software Freedom Law Center and heads the Software Freedom Conservancy. He is fun to watch and listen to because he walks the tightrope between creative, carefree developers and cautious, legally-minded lawyers. Linux.com talked with Kuhn a few months ago, but he says lots more in this 30-minute video than in that interview -- including plenty of thoughts on how businesses based on free software can (and often do) turn a profit, plus some comments on how and why open source is helping the next generation of programmers develop and improve their skills.
