"Flighty Tracker is an aggregator that helps users to manage feeds of information related to a specific topic. It was built in direct response to the 2010 earthquake in Haiti to help sift through the torrent of news, rumor and controversy that followed. It helps help filter and organize an otherwise unmanageable river of news. Flighty is for people running Ushahidi who need something to aggregate incoming SMS from Clickatell, FrontlineSMS, or any other XML source etc. It's intentionally lightweight and stripped down. For more a more advanced solution, look at Swiftriver which uses a combination of crowd-sourcing and algorithms to determine the veracity of incoming reports."
