This rising social-networking tide overseas is, of course, lifting all boats, but none higher than Facebook. With 132 million unique visitors in June–up 153 percent from the same month a year earlier–Facebook is now the largest social network in the world. Its biggest rival, MySpace, had 117 million users in June, a 3 percent increase over last year. Why the gross disparity? Thanks to its new Translations application, Facebook now dominates several markets where it was once relatively unused. In fact, nearly 63 percent of Facebook’s users are outside North America. That’s the sort of thing that happens when you manage to translate your site into 89 languages.
