Great site.
If you ever want proof... well, go through your YouTube subscriptions and ask yourself how many of the channels are by people from the US. For me the number is about 50-60%.
Oh? You don't have any Baidu video subscriptions?
Are you sure it's the "internet" assuming that you're an American? Or is it just that you hang out on the internet where Americans tend to hang out?
Russian/European version of Facebook is called "VKonakte". Chinese version of YouTube is called "YouKu", Chinese Facebook is called "Weibo". In those places you will barely find any American users or people that speak a lot of English.
