This book is geared more towards readers who are new to blogging. Those who have blogging experience probably won't find much new information reading this book.
Besides the basic introduction to blogging aspects though, Houghton included many reference to various blogs that serve as good examples for the points she was trying to make. I think that is very useful, especially for readers who read the ebook version on their tablets. Reading Blogging for Creatives
on my iPad made it really easy to visit the links that interested me before going back to reading the book. So, I'd say this is definitely a book that benefits from being an ebook over a printed copy.
