Twitter's 20 billionth message didn't make much sense, but it spoke volumes about the rapid global growth of the microblogging service. It came at 12:44 A.M. Sunday (1544 GMT, 11:44 a.m. EDT Saturday) from user “GGGGGGo_Lets_Go” in Japan, where Twitter has exploded in popularity over the last year. The tweet itself is hard to decipher, since it appears to be part of a longer conversation between two users. “So that means the barrage might come back later all at once,” wrote the declared graphic designer and avid fan of the Tokyo Yakult Swallows baseball team in Japanese. It didn't take long before GGGGGGo_Lets_Go was inundated with congratulatory messages from around the world for hitting the social networking milestone. The user bio changed shortly thereafter.
