If you live in Japan you may have heard of the social networking site 
Mixi.  If you speak English, you may have heard of MySpace.  There 
sites are good, but they are large and unfocused.  I started a social 
networking site that is for intercultural understanding and languag 
exchange.  It is small and has an at-home feel.  Check it out.
