The situation in Iran is still abuzz on Twitter, but what can the Iranians access online? HerdictWeb’s got a list, built on reports from users. If you can, do contribute to the list, and read the Herdict Blog post on the matter.
You might also be interested in the collected stories about Iran by GlobalVoices, frequently updated on a geographical level. Also, this BusinessWeek story (Techmeme discussion) claims that social media hasn’t been instrumental in getting Iranian protesters to the street, SMS texting and word of mouth has been. Hardly surprising, but the #iranelection buzz almost made it sound like that was the only means of communication at one time, which of course was never the case.
