1. Andrew Sullivan's The Daily Dish - has been all over the story and is an excellent resource
2. National Iranian American Committee's NIACBlog - providing translations from Farsi to English of Twitter and Facebook reports of what's happening in the country. Fantastic resource for on the ground reporting.
3. Tehran Bureau - A project of the Harvard School of Journalism in an attempt to provide in-depth coverage of Iran. There spot reporting has been invaluable.
4. NYTimes The Lede - Have provided constant updates from NYTimes reporters on the ground in Tehran. They've also compiled other reports from around the internet.
5. BBCNews - Another great resource for on the ground reports from the Western hemisphere's premier broadcast organization.
6. DKos Clifflyon's Diary - It's been ahead of the curve today and contains many of the important developments so far today
7. Images of Tehran Rising Provided by Al Rodgers
The Revolution will be Twittered Live
8. Student Twitterfrom the opposition live from Tehran. Detailing attacks on the university and reformist strongholds by government thugs. Can't vouch for accuracy but it seems like it's authentic and has been linked to by other blogs.
9. Mousavi Campaign Twitter - Some of it is in Farsi (Persian) and some of it is in English. We believe this is the official campaign Twitter."
