We've said it on this blog many times, when it comes to creating content for your business, you should always give preferential treatment to those working in your business. Some companies will hire ghost-writers to create content, but their efforts rarely ring true, as they don't know the business inside out like your experts do.

Unless your staff are all now actual robots, I wouldn't recommend that route. The future might prove both Jay Acunzo (author of the article linked to below) and me wrong though!
