Alot of people on Twitter are retweeting information as it comes in, and I have been a bit too, though somewhat warily. By all accounts, the brave people microblogging in this way risk arrest or worse, and it's important a) not to give away identities and locations and b) to be sure that you are retweeting actual information about rallies etc, and not disinformation spread by the Iranian government. The great strength of the internet which allows people in a situation like this the freedom to express what is happening, is also it's greatest weakness: with such a plethora of information available to us, it is often extremely difficult to find out what is going on.
Twitter appear to be doing their best by posting a list of potential dodgy twitterers here, but it's still difficult, so I am trying to be selective about what I send on.
Having said that, what I find incredibly heartening about this situation, is both the mass of support across the internet for the people of Iran, and the staggering courage of those sending out information. We don't know yet how this will pan out. I am sceptical about it being another Velvet Revolution, because sadly the Basij militia have already shown what they are capable of, and I fear this may still be a Prague Spring. However, thanks to the courage of the bloggers, we will know what happens for good or bad, and whatever the Supreme Leader says, the world will know at least some of the truth.
Twitterers are posting green avatars in support of Iran. Opinion is divided as to whether this is a futile gesture or not. It may well be. But I think at a time when Ahmadinejad would have us believe the Holocaust didn't happen, America the Great Satan is bent on its destruction (and let's face it America hasn't actually held the olive branch out till Obama took over), I think it's important that we in the West reach out a hand across the internet to the brave people of Iran and show them as Stephen Fry put it so simply: Iranian govt should at least know we're watching & we care. We're not imperialists, we just care.
