Are the Social Media about to shape history again?

After the landslide victory of Barack Obama where, next to the will of the American people for change, the Social Media played a tremendously important role it seems that these media will shape the history once more. The death of a female student during the current demonstrations of the people of Iran against what they see as rigged ballot has become first page news thanks to a video posted in YouTube and on Twitter. The shocking pictures of the last moments of this Iranian girl captured in a cell phone video have already become worldwide news and will most probably have a decisive effect on Iranian history.
