Business and books - Do they go together

Let's talk business and books! What do they have in common? Do they go together? 

Do you have a business?  Do you feel there is enough information about what you do that you could share in a book? Are you an expert at something? Would it make an interesting book?

Would a book, written by you, help to promote who you are and what you do? Will you boost your credibility, bring you new customers and/or help you to build your business?

Join us with your thoughts and comments and see if perhaps YOU should write a book!?
