A few days ago, the Free Software Foundation announced a new video explaining Free software in simple terms. The video named User Liberation is 3 minutes long, and I recommend showing it to everyone you know as a way to explain what Free Software is all about. Unfortunately several of the people I know do not understand English and Spanish, so it did not make sense to show it to them.
But today I was told that English subtitles were available and set out to provide Norwegian Bokmål subtitles based on these. The result has been sent to FSF and made available in a git repository provided by Github. Please let me know if you find errors or have improvements to the subtitles.
Update 2015-02-03: Since I publised this post, FSF created a Libreplanet project to track subtitles for the video.
