Groups, Tags and Categories

After looking at a few tags such as internet and wiki I also tried copyleft and then I hit the link for "Try searching for "copyleft" in: Groups" by mistake. That led me to the copyleft group. Sadly only one member. I had previously taken a quick look at Groups and not seen much of value.

Categories
The YouTube categories do not seem very.....comprehensive?

Autos & Vehicles
Comedy
Entertainment
Film & Animation
Gadgets & Games
Howto & DIY
Music
News & Politics
People & Blogs
Pets & Animals
Sports
Travel & Places

I'm wondering if concepts such as copy left will ever find a role in YouTube. Maybe there could be some kind of competition for copyleft videos.
