Summary Box: Twitter censorship plan rouses furor

THE SPARK: Twitter, a tool of choice for dissidents and activists around the world, unveils plans to allow country-specific censorship of tweets that might break local laws.

TWITTER’S POSITION: Previously, when Twitter erased a tweet, it vanished throughout the world. Under the new policy, a tweet breaking a law in one country can be taken down there and still be seen elsewhere. The company describes it as a step forward.

RESPONSE: Critics ? in a barrage of tweets ? propose a Twitter boycott and demand that the censorship initiative be scrapped.
