China - Microblog Commenting Restored - NYTimes.com China's two biggest microblog sites resumed normal service on Tuesday after a three-day ban on posting comments that drew complaints about censorship amid the country's worst high-level political crisis in years. The suspension of the comment function on Sina's Weibo.com and Tencent's t.qq.com followed a flurry of rumors online about the downfall of a prominent Communist Party figure, Bo Xilai. The authorities have closed a dozen Web sites and detained six people for circulating rumors of a coup that rattled Beijing. The two companies said in statements on their sites that the shutdown was aimed at "cleaning up" illegal and harmful information posted on some microblogs but gave no details.
