Never seen any of Avatars but I see nothing that would interest me. I've understood they're stories about some imaginary creatures. Why should I care?

The best in YouTube are probably classical music master classes that give you an incredible insight on music. No hope seeing anything like that on television. Instructional videos are good too. Like installing stuff on computer and fixing bicycles.

Personally I never watch anyone speaking. Seeing a talking face somehow creeps me. Maybe its a bit sensitive but I see watching anyone eye to eye as a game of social dominance.
