As many of you may know, Iranians are using Twitter (http://twitter.co...) to communicate and organize because their government shut down other methods of grassroots communication. If you have a Twitter account and change your time zone to +3:30 GMT and your location to Iran, you can help confuse the secret police and buy the Iranian people some time--perhaps even save lives. If you DON'T have a Twitter account, maybe this is the time!
Shoot for the moon. Even if you miss, you'll land among the stars.
