More on Twitter as an event source

I have written sometimes ago about creative use of Twitter as an event source; the recent days riots in Iran, where strict media censorship is imposed, indicate the role of means like Twitter. It turns out that Twitter has a major role in communicating to the outside world what is happening in Iran. The state department has asked Twitter to cancel scheduled maintenance to keep Twitter up and running all day. To all people who doubt the power of what can be expressed in 140 characters, it seems that Twitter is becoming a major event source in our universe, due to the ease of connecting it from everywhere. Of course, one can abuse any event source and send false information, but the mass quantity exposes the truth. I'll revisit text messages as event sources in later posts.
