I don't see it much as a 'learning German as a language' video, but a 'learn an aspect of German in-depth'. I guess it would be geared to people who have a fundamental grasp of German, usually.
And weird nuts like myself that enjoy learning about words. And remembering to use a couple phrases that amused me.
There are already lots of 'learn to speak German' videos around. I think Tom is trying to do something different.
