Twitter: 221,744 “Iran” tweets in one hour
Blogs: 2,250,000 blog posts on Iran in 24 hours
YouTube: 3000 Iran videos uploaded in one day
These trends clearly demonstrate that social media has been front-and-center in the Iran election protests. The Iranian government has reportedly been trying to censor some of this communication, but clearly people are finding ways around it. While we know a great deal about what’s happening in Iran, we have almost no idea how it will affect the outcome. This may be the biggest question that remains to be answered.
Twitter search for the hashtag #iranelection is the best way to track what is happening now. Not five minutes or five hours ago, but now.
