Iranian protesters need one million people on Twitter to change their time zone setting to Iran (find Tehran on settings tab). It’s an easy thing you can do.
Meanwhile they tweet advice to wash Basiji marks off doors with oil so protesters will not be attacked, to spread oil or sand piles to slow them, to rip down streets signs to disorient them, to remove SMS cards, carry Holy Korans for protection, go to embassy hospitals because Basiji are arresting injured at hospitals, to wash burning liquid sprayed from helicopters with lemon juice, and on and on.
I think I can change a time zone. How about you?
P.S. Google Earth has already updated maps of Iran and is working on getting more pixels and updates. Way to go.

Time Zone and written location changed 😉 I am assuming this is to confuse the b*st*rds in the gov’t of Iran who wish to interfere with opposition tweets and/or track down and beat dissidents.
You are exactly right. At least there is something we can do.
