When a busy high profile public figure such as, let's say, Barack Obama gets a Twitter account, it's pretty much granted that he doesn't have the time to actually 'tweet' - therefore the situation calls for a GHOST TWITTERER (similar to a ghost writer), a person in that person's staff, who does the tweeting for him (her).
Neophite Twitter subscribers that flood followers ( usually relatives or family )with nonsensical tweets escalting in triviality with each subequent tweet from their counterpart.
TwitterDee : Big sale at Macy's!
TwitterDum : Sales at Macys are great!
TwitterDee : Macy's has better sales than anyone!
TwitterDum : Macy's has the best sales ever.
