On Sunday I watched the Ghostwriter, which is a superb thriller which doesn't require much thinking. And with Pierce Brosnan and Ewan McGregor in the lead roles, it can even be forgiven for not inspiring you to pick up a pen and paper and begin writing - or ghostwriting as it may be.

Having said that, ghostwriting is becoming more and more popular, not to mention lucrative, as celebrities and media gurus alike seek to free up their time, by outsourcing their writing needs to a 'ghostwriter'. I recently read an article in the Entrepreneur magazine, where popular (and millionaire) coach, author and motivational guru, Robert Kiyosaki's ghostwriter was interviewed. That's right  - she's the one who writes his blogs, twitter thoughts and facebook comments.

 A bit disappointing, but understandable as most coaches and speakers don't have the time to write their own marketing material. The same holds true for a lot of entrepreneurs. Most of them will like to market their brand, but poor communication skills prevent them from doing so. Step in the ghostwriter, whose job it is to make them look good. For a fee. Ghostwriting is not cheap and a good ghostwriter can command double the normal writing fee. If you can adopt your client's voice and take ego out of the equation, ghostwriting might be right for you.

While the debate rages on - is a client who uses a ghostwriter 'cheating' his audience, or not? - ghostwriters continue to take on growing challenges and prove their worth in an expanding and competitive trade.
