Orkut, which became largely Brazilian, is the classic example. There were some good articles about how that arose but cant find them (maybe the dead link from http://tech.slashdot.org/story/04/07/17/2243232/language-tempest-at-orkut http://tech.slashdot.org/story/04/07/17/2243232/language-tem... ?). In that case it was partly about language initially, Google allowed mixed languages in threads, and Portuguese put off the English speakers but not so much the other way round.
