The Internet is giving a boost to the book business at least in Japan, where online discussions are currently being published as books. The fad started back in October, with “Train Man”: a shy young man asked for online advice on how to ask out a girl he met on the train in Tokyo; after getting online dating tips and encouragement and two months later, the girl the sage words were transformed into a book, which has sold 555,000 copies. The beauty of the tome is that it’s published as printouts of message boards and blogs, complete with Internet lingo and silly emoticons. Not much editing required.
