Ghost Twitterer

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).

It's pretty obvious he has a ghost twitterer.
