> If you look at wikipedia's contributor stats it's like 70% white†, college aged males. (Actually wikipedians are like 87% male. http://feministing.com/2011/02/02/why-are-only-13-of-wikiped.... )

When an all/mostly black country invents something like the Internet, and then creates a website like Wikipedia, and then most of the nerds it attracts to administrate it happen to be black male nerds, then, yes, you'll see a different demographic mix. But until that happens, you'll see demographic trends that are likely (and reasonably) going to be heavily influenced by their starting conditions.
