Informer or Meformer: Which twitter type are you?

There was an interesting comment posted yesterday by Bradley Hughes (thanks mate), highlighting a recent study from Rutgers University. 
The study examined the message content of 350 randomly selected twitter users and found two key clusters (or types) of user, Meformers & Informers. 
According to the researchers, "twitter users represents two different types of content camps; the majority of users focus on the self, while a smaller set of users are driven more by sharing information." So the question is, which twitter type are you?
