NYT covers role of social networking sites in Iran

According to today's New York Times, a presidential aide asked Twitter if they could postpone scheduled maintenance that would have temporarily shut down the site, underscoring the role Twitter has been playing in the Iranian protests.  The article talks about how Twitter has been used by those protesting, but also about Twitter's (and YouTube's) value for US diplomacy and for the media, where Iranians have been able to release videos and pictures---information that is becoming increasingly difficult for journalists to obtain.
