I don't know much about music creation - my thing is GNU/Linux installation and support. The more I help to convert people to GNU/Linux, the more I run into people who want to use things like ProTools. Of course I did some searching and found Ardour. Unfortunately, these folks are set in there ways, and I don't know enough about music creation to teach them. Something like UbuntuClips, YouTube, or perhaps many others could be used to show video clips of how to perform some basic tasks. My guess is that the more people can see how to perform certain tasks, the more people will get involved with Ardour.
