I just recently switched over to Smashwords, finally have my first novel in multiple formats. Had a hell of a time with Amazon. They totally screwed up my search, not putting a release date on it. Never did iron out the search part to have it listed as a series. Took over a month to show up under fantasy, so I lost out on the first 30 days, nobody even saw it was there, really sucked. Went Smashwords a few days ago and had sales right away. Should have went with them right from the start. Being up front with the authors and readers, maybe helping them with what works would make it so much easier for all of us. IMO
