I suspect that some writers can’t afford to pay for more than two or three decent covers, for their e-books. They say, a decent book cover attracts a reader’s attention. By grabbing him or her back of the shirt collar. Yanking him/her to the author’s book, and say. “Hey, get over here and read this.”
Some readers prefer book in paper format and hard cover. In my opinion, both formats traditional and e-books are just fine with me.
Of course, from what little information I garnered, being an Indie writer is an interesting journey. With two sides of the coin.
The writing business is a cut throat industry. One of which, critics would mercilessly give a writer thumbs down. Not to mention polishing the draft, via editing and proofreading. Feedback is another issue.
A friend of mine once said, “For feedback, you’ll have to limit the pool of readers to three. No more than that.”
If memory serves me correctly, or had fled to the bush.
As a saying goes, with feedback is basically a person would tell you what works, and when something is not working.
