Tehran Twitters

Not to be too cynical about the on-going revolutionary movement in Iran, but the hype around the use of Twitter is kind of nauseating. On one hand it is a way to get information out of repressive political borders. On the other hand it is a totally unreliable source of information created for the use of Americans to gossip about themselves. To lend such validity and credence to this texting format is a mistake that will eventually blow up in the face of cable news. Just because something is said over and over on the Internet does not make it true, or maybe it does. As information multiplies it seems to become less informative and more noise. How hard would it be for a government to manipulate the Twitter-sphere?
