Benny's Japanese Mission

Benny Lewis has announced that he's aiming to get to B2 level in Japanese (with emphasis on conversational skills rather than reading and writing) in the next three months.  Should be entertaining to read, and he does good videos.  Previously on his site: Scott and Vat try to spend a year speaking only Spanish/Portugese/Chinese/Korean; no English talking at all.  This is probably brilliant for fluency but would drive me insane.
