One of my favorite example’s of using Web 2.0 for language instruction has been the use by our Japanese department of the social networking site Mixi along with our Skype exchanges on the Mixxer to intergrate interaction with native speakers throughout their first three years of Japanese.  For a while, I had hoped to imitate this interaction in other languages by combining their language exchanges via Skype with written exchanges on other country specific social networks as well.  Unfortunately, it seems Facebook is well on its way to ruling the western hemisphere at least.  China, Japan, and Russia may keep their local networks for a while, but it’s going to hard to stop Facebook’s momentum.
