The servers that house Twitter, Facebook and BlackBerry Messenger don't have a political, social or legal agenda. Their job is simply to transmit what people post and deliver it to people who want to see it.

5 Days of War is a new action movie set during the 2008 Georgia-Russia war.

On October 6th, the Cuban Interests Section (aka the Cuban Embassy) will launch a clever bit of public diplomacy by opening "Hemingway's Bar."
