Take a look at this link -http://www.booktrade.info/i.php/34122 and read about some of the realities of self-publishing. One of the biggest self-publishing companies admits that is has published the worst collections of poetry the world has ever known - not that the world will read it as most books only sell to friends and family of the so called author.
It's as a writing friend said to me the other day, 'The public are now reading the slush pile'.
And a non writing friend said she had been given a novel to read and if it had been her first she'd never have read another book. I knew the author and had to explain about real publishing and self-publishing. The public don't know the difference but most know good from bad.
I'm not saying all self-publishing is bad but do read the link. I could have written it myself, but didn't. And I didn't ghost it either!
