Timeline of events in Iran, but also
history and important (cultural, economic, etc) facts via
kuwdora because you can't truly understand one without the other.
Meanwhile, if you're using twitter - help cover the people who are getting information out via twitter (#iranelection) because they're being rounded up. Change your time zone and location settings to Tehran, Iran. It makes it at least a little harder to track them.
And here, Youtube and Twitter both prove how they're truly helpful and how powerful Web 2.0 can be. People are getting out videos and information via those social service sites, information that would not make it out because
foreign journalists are banned from covering the protests.
People are being killed. You can't afford to say you don't care. Even just passing links along is better than just scrolling past, it does help.
