Like many, I think, I've been watching the footage of the massive demonstrations and state brutality and the internet updates (Now here's a real use for Twitter, to put all the banal, compulsive over-sharing of politicians and correspondents to shame) coming out of Iran over the last few days. It's all worrying and exciting and very confusing to me--how and to what extent were the elections rigged? Is there any chance that this outpouring of indignation will have an effect? 

I do think President Obama struck the right tone. Since we are (thankfully) not currently planning on bombing and invading Iran, there is no point is making strident ultimatums or threats--they will just be used by the clerical regime to tar their opponents; they're already accusing the U.S. of interference.
