This is off-topic but too amusing to pass:
“Japan is enjoying the richest and most varied form of Twitter usage as a communication tool,” says Daisuke Tsuda, 36, a writer with more than 65,000 “followers” for his tweets. “It’s playing out as a rediscovery of the Internet.”
One reason is language. It’s possible to say so much more in Japanese within Twitter’s 140 letter limit. The word “information” requires just two letters in Japanese. That allows academics and politicians to relay complex views, according to Tsuda, who believes Twitter could easily attract 20 million people in Japan soon.
