One of the most well known platforms for digital publishing is Amazon's Kindle digital publishing - anyone can publish a book here -It simply means authors can sell their digital version works on Amazon.com. For the writers who already have a dedicated following, it would be a good idea to utilize the audience source to publish and sell books. In this case, self-publishing may present long-term challenges to book publishers, as they are now losing those potential and probably profitable works.
The problem with this is that it is often not the best writers who are the most successful here, but rather the best at handling marketing. I've lost count of the amount of times I've read a massive selling author, only to discover that the books are cliched, badly written and hardly engaging. Still these books seem to attract scores of reviews and sell like crazy. Go figure!
That's not to say there are not some great writers out there who have mastered selling through Kindle - there are many many of them. but the fact remains that it is getting increasingly difficult to get noticed in the crowded digital marketplace. There are some excellent books out there that have yet to achieve the sales they deserve.
Writers going down the digital publishing route need to beware.
