It may not have lead to changes inside Iran yet, but it did show the world that Iran isn't just another country full of towelheads and sandniggers intend on killing us, giving hope to a peaceful solution to the nuclear crisis.
And that is going to impact Iran.

I am not implying (nor the linked FP article) that Twitter was insignificant in spreading the news around the world. It sure did one hell of a job and undoubtedly helped get the world’s attention to the Iranian’s ordeal. I am just downplaying the role of Twitter in facilitating the Iranians in physically organizing the protest (It contrast to the popular perception that Twitter played a critical role especially in this regard). Twitter was nearly non-existent in the streets of Tehran. That’s what the FP article is suggesting.
