The Chinese government began blocking access to the popular blogging site LiveJournal on Friday, cutting off its citizens from the roughly 1.8 million blogs the service hosts. SixApart, the company behind LiveJournal, says there are 8,692 self-reported Chinese bloggers on the site, a number that's likely low since it's based on information volunteered in user profiles. LiveJournal announced the block Monday. Ginger Tulley, director of worldwide strategy and analysis for Six Apart, says the company isn't certain when the censorship began. But the site GreatFirewallofChina.org, which tests connectivity to popular websites from within China, first spotted the block Friday.
