Boy you really jump to some conclusions.Thanks for that video link, although I realize why he turn the comments off because he is likely getting tired of most everybody making a comment questioning why he doesn't go out and buy a $10 tripod instead of trying to do everything with only one hand. I will never understand people who make YouTube videos and why they do that.
"He" is me, and as far as I can tell the reason comments are disabled is because I selected the "made for kids" option on that one, and Youtube automatically disables comments for kids' videos (probably a smart policy if I am understanding correctly).
I have no tripod because my Youtube channel could literally not be any more half-assed. If you are looking for highly produced videos then by all means go elsewhere.
