Helping the Iranian Protestors:

This seems like a good idea for Twitterphiles:

Do you twitter? Change your twitter setting to GMT +3:30 (Tehran time) and your location to any city in Iran. If all of us are Iranians then it is a little harder for government censors to track down Iranian tweeters. (See list of Iranian cities at http://is.gd/13UCt.)
