SmartMobs describes a report from the China Digital Times on the twitter mobbing of a virtual wall set up by KulturProjekte to commemorate the 20th anniversary of the fall of the Berlin Wall. Using the twitter hashtag #FOTW, Chinese ‘netizens’ have bombarded the site with calls to end State censorship of the Web.

Which I wonder (should the latter happen) would have the greater historical significance; the fall of the Beriln Wall or that of the Great Firewall of China?

Blog Action Day is an annual event held every October 15 in an attempt to unite the world’s bloggers in posting about an issue of global importance on the same day. This year’s issue is climate change, and it falls on the day as it was revealed that the Arctic Ocean will be almost entirely free from ice within a decade.

The Catlin Arctic Survey, completed earlier this year by a team led by explorer Pen Hadow, represents the most current research into the condition of Arctic ice. Peter Wadhams of the Polar Ocean Physics Group at the University of Cambridge, who analysed the data added “the summer ice cover in the Arctic will completely vanish in 20 to 30 years time. There won’t be any sea ice there at all.”
