I think the problem more selling than publishing. Bookview Cafe is awesome, but not all that high traffic, and a terrible choice for a new author (and I have no idea if it will even take a previously unpublished author), Smashwords is a swamp of bad with some islands of good, and both are small. They are also the only sites that universally sell DRM-free books.

OTOH, Kobo sells some DRM free books, and most of its books are at least easy (ie possible w/o advanced skillz) to download, at which point DRM-stripping is relatively easy, so even from sites that sell DRM'd books (which I only recommend buying if you possess simple tech for stripping it off, and I still always buy DRM-free options if I can), this book was a royal pain to purchase and actually download.
