There is link on here a few comments up that is a link to Hugh Hewlitt and he has a list of Iranians tweeting. However, I have been getting mine from #IranElections, most of them are NOT from Iran but now and then I see a few.
This one refreshes itself, and used to have messages from Iran, but I haven’t seen any in a few hours. I just let it run in another window...

I’ve been following a lot of them on twitter...a lot of them signed off a bit ago to get some sleep...
