It could be that Twitter research is popular because Twitter data is free and so accessible. That's okay. Gift horses are just as good for riding. The best, latest entry in Twitter research is the handiwork of Meeyoung Cha from the Max Planck Institute for Software Systems in Germany. Cha called her paper "The Million Follower Fallacy," a term that comes from work by Adi Avnit. Avnit posited that the number of followers of a Tweeter is largely meaningless, and Cha, after looking at data from all 52 million Twitter accounts (and, more closely, at the 6 million "active users") seems to have proven Avnit right.
