Iran
"Only 10 hours left until the Iranian people finally disobey their dictator. History is watching. Let's make it proud. @kapanak - June 19"
The Revolution will not be televised, but it will be tweeted. When Iranians took to the streets in June to protest the reelection of President Mahmoud Ahmadinejad, the government quickly severed links from the streets to the outside world, except for a steady stream of tweets that managed to seep through. Beyond celebrities and status updates, this was Twitter's real moment of 2009: 140 character glimpses of life, fear and death on the streets of a country in turmoil. The demonstrations were ultimately quashed, but for weeks, many around the world helped further their cause on Twitter, tagging posts with #iranelection and changing their own user icons green, the color of challenger Mir-Hossein Mousavi's party.
