This time tomorrow, Iran may have a new president-elect. The polls opened just over an hour ago, and if you're awake, you can get tech-related updates on Twitter via @Iran09:

Mousavi's #election site had been under DDOS attack last night from #iran gov.

SMS system is still down in #iran, two hours before the #election

If you happen to be in Iran, a few of us Americans are requesting stories about your experience: Andrew Sullivan has asked his readers to send him "first-hand accounts of campaigning and voting so Dish readers can get a more concrete sense of what the mood is," while the New York Times' Lede blog has a form that lets users submit pictures and videos from the polls. Both sites will post the submissions later for all to see.

Finally, Berkman researchers John Kelly and Bruce Etling just posted a graphical analysis of Iranian blog chatter, broken down by candidate support. Surprise: the top contender, Mir-Hossein Mousavi, is more popular among bloggers than Ahmadinejad.
