At this point Twitter is anything, but unknown. Everyone from techies, journalist, to celebs took an interest in the newest to the Social Media Networking platform. Just like all the other forms of social interaction on the web, people start going viral with it. Sean Kingston is one of the first to make a whole song about Twitter users. Singing about RT, people with 5 followers, and following people on their Twitter pages. It's the Twitter love song of the century :)
