From Michael Nelson via email:

The GNU/Linux operating system Ubuntu has formed a screencast team and is generating a bunch of videos on how to install and use the software. The second they create a screencast on how to create a screencast in Ubuntu is the second I install it. I can use Firefox, OpenOffice, GIMP, Audacity and Scribus pretty well now. I am almost there, almost free. Just a video editor, screenrecorder and Blender 3D animation to go.  I wonder how long before there is a viable alternative to Flash?
