Readers are as fickle as they are astute. Don’t miss that! Do NOT ignore this!
Readers like what they like and they rarely deviate from that. There are books that I like in e-format and there are books that need (not want!) to have in physical form. One of the things that is great about having a book in dual format is you will appeal to a greater audience!
APPEAL IS A PART OF MARKETING!
I cannot tell you how valuable it is to consider the appeal of your book so you know just how to market it! As great as it is so have finished a book, it is even better when you can sell a lot of them! Did I mention that e-books are good for the environment? They are!
Besides, the readers are going to be your best judge.
