"Unfortunately, an impending disaster is sometimes the impetus for naysayers to see the worth of a service like Twitter. The hashtag being used on Twitter to track the tweets referring to Tropical Cyclone Yasi is #tcyasi. I've been following this hashtag today, and as the cyclone gets closer to the east coast of Far North Queensland, I am receiving more pertinent information there than what I am getting from news organisations like Channel 7 and their very sensationalist Today Tonight program."
