Do the Chinese video surfers click more ads than the YouTube audience? With all the talk lately about YT having trouble making money, or rather Google having trouble making /enough/ money with YT, how is it that all these clones are getting so much VC?
Is the speculation wrong or is the market different in the far east?
I can't answer your direct question, but if you're trying to infer whether the Chinese video sites are profitable or not, I can say that I've heard they are all losing money at the moment and the general strategy seems to be a war of attrition.
