Twitter, micro social networking site has had its 20 billionth message posted. The landmark and rather opaque tweet was sent at 1544 GMT Saturday by GGGGGGo_Lets_Go, a Tokyo graphic designer; "So that means the barrage might come back later all at once." Twitter reached its 10 billionth tweet, in March this year, and less than five months to double it.
GGGGGGo_Lets_Go later posted: "Looks like I posted 20 billionth tweet. I'm getting replies from people all over the world. It's scary. What're the chances? Maybe I'm going to die. "Is it more amazing than winning the lottery? I thought it was a joke."
Japanese send nearly 8m tweets a day, about 12% of the global total and second only to the US, according to the San Francisco-based micro-blogging service. Evan Williams, Twitter's chief executive, travelled to Tokyo earlier this month to celebrate the service's success in Japan.
