Twitter data usage by U.S. Library of Congress

An interesting article that fits well with our class discussion on Twitter. As we debate over commercial benefit of twitter data, The U.S. Library of Congress has announced that it will be acquiring the entire archive of Twitter messages back through March 2006. According to another article on its site "Every public tweet, ever, since Twitter’s inception in March 2006, will be archived digitally at the Library of Congress". It will possibly use this massive data to discover patterns of social interaction.
