it seems to me this problem concerns only those who don't speak English well
all the rest are so free to doqnload dozens of videos every day (even if they are about nothing)
I have noticed that it' a common thing for foreign countries, and people aren't shy before a cam at all, in Russia, for instance, it's still not so popular, that's why Russian people download videos here not so often.
And a language bareer means a lot.

But you're right, it's popular, and it's great to follow this tradition, if you speak English well
