Ghost Twittering

Ghost Twitters are out there, but it's not what you think.  It's not dead people, but - far worse - celebs:

someone has to do all that writing, even if each entry is barely a sentence long. In many cases, celebrities and their handlers have turned to outside writers — ghost Twitterers, if you will — who keep fans updated on the latest twists and turns, often in the star’s own voice.

Because Twitter is seen as an intimate link between celebrities and their fans, many performers are not willing to divulge the help they use to put their thoughts into cyberspace.
