*THIS INFORMATION HAS CHANGED IN THE LAST DECADE.
When I first considered Kindle I refused it, as it seemed too hard and I heard and read bad things in the kindle forums where there were
troubles with payments and people not getting help. So, I decided to go with Smashwords for ALL of my eBook formats, however, sales have been slow, and I always had this inkling that it was because I had not published on Kindle. I just relied upon the Kindle format through Smashwords to get me through.
Kindle How To Publish says
Great info. Thanks! Kindle publishing is effortless, and requires only a computer, an internet connection, and an e-book written in the appropriate format. Kindle self-publishing through Amazon takes care of everything. Not only is Kindle self-publishing effortless, but it doesn't require an agent or traditional publishing firm. Very interesting indeed.
