I think if you want to video for your own personal library, fine. But to post on youtube and other such sites - I don't think that is cool.
If I got my bu-- kicked by some stud - I wouldn't want the whole world to be able to watch it 24/7/365. Potentially, year after year . . .
I'd want to learn from it, forget about it and move on. Not be constant laughing material for some other dude sitting in front of his PC at his house.
