Here comes another ban from China on Web services; Twitter, Blogger and Bing along with numerous other services have been banned. These bans aren’t something new as earlier the country had banned Plurk as well. I wonder why is it that the country has got such a harsh policy on web services that it keeps banning one or another at various times. Perhaps it considers itself to be responsible at safeguarding its population from external influence. Anyone with better reasons?
