The Sociology of Twitter

With news that Twitter's entire backlog of tweets will be headed for the Library of Congress, will this open broader channels for sociology-based research using the micro-blog medium? I'd definitely be interested in a study on celebrities who have foregone their agents wishes and posted incriminating tweets and how this effects their careers. Really, I think this opens up possibilities of assessing Twitter for usefulness - what are people actually Tweeting about and what relevance that holds for the individual, the local community and the global community. There's a lesson in their for students on their contextual use of the internet - what is the bigger picture and what is it really all about. The transparency of posting online content should open our eyes to something more - it makes us community members on a global scale.
