If you've read my swineflu analysis, some of this should make sense. I ran a search on '#iranelection OR Tehran OR Ahmadinejad OR Mousavi' in Twitter for the period between Friday and Sunday evening. From the 79,957 results I got back, below is some graph analysis of what came out.

I'll mostly let the results speak for themselves (since I'm not well informed enough on Iranian politics to make much comment), but I will point out that there are a huge proportion of retweets to tweets, roughly a third, as indicated by 'RT". I usually see about a 1 to 10 or 1 to 20 ratio. That's massive.

Also, stopahmadi is far and away the largest authority shown via the HITS algorithm, which might indicate that it's the opposition who are getting the advantage of Twitter. Not shocking, really, but maybe a bit more evidence for that. Of course, the whole world is tweeting this, and Ahmadinejad is not much beloved outside his country, so take all of this with a large grain of salt.

The "hub" scores look a little flat (there's often a biggish gap between the top hub and the 10th top hub), but I can't adequately explain that either. Top hub seems to be an American conservative news tweeter.

The numbers (biggest scores at bottom of the lists--I really need to reverse those, but whatever):
