I've not had YouTube around when I was learning karate, so I don't know if I'd be using it if I was learning karate now. However, I did use it to learn some dance moves, and although I was just sitting in my chair and watching it, it did help a lot with many "aha" moments and practiced them later. Sure, there is a lot of crap on there, but I can filter that myself. Things in karate that you could just learn by watching without much training are pressure points and how to get out of someone's hold. The other stuff needs training (especially conditioning), but a good video can give you directions for how to do it.
