For her study, #Memstorm: Twitter as a community-driven breaking news reporting tool, she looked at real-time flow of information on Twitter during the storms that hit the region.
She highlighted how the hashtag, #Memstorm, did not come from the news outlets but from the public.
Fox tried to created its own hashtag to brand the storms, but Brown noted there was an audience backlash against Fox.
The most common type of tweets were direct observation, essentially eye-witness reports. There were also examples of people asking questions about reports and rumours to verify information.
For retweets, Brown found there was also a significant amount of material from the media, especially TV stations.
Brown found there was a sense of people commiserating with each other on Twitter, expressing emotion and sympathy.
There were also attempts at humour around the storm on Twitter.
She suggested the role for journalists in an ambient journalism environment was verification, amplification of the best stuff, engaging with audiences and providing very specific location information.
