Ghislaine, the point of the OP is that Twitter does nothing for Iranians, and everything for our benefit. Iranian protestors are being beaten, shot and killed, but if we tint our twitter profile green we're somehow taking part? Imagine the look on Iranian children's faces when they are told that a bunch of Canadian students with green avatars have changed their timezone to UTC +3:30 in solidarity. What comfort it must give them. If a million Iranians are marching in the street, how many do you think have iPhone with a twitter app installed and have the techno savvy to use IP proxies?

Here: Iranians, as always, can take care of themselves. They don't need a cheeky American startup retweeting the latest bullshit.
