eBooks are definitely taking over. Don't ignore the eBook revolution -- it's happening. While print is currently dominating, don't expect that to last past the next two to three years. The industry will continue to shift much like the cell phone put the land line into check. Yes, there are still land lines, but I don't even use one in my business. Watch that trend to continue with eBooks until print is strictly "novelty" vs. norm.
Authors who fail to support their books will not win the game. Let me give you an example. Josh Mathe, author of In the Footsteps of Greatness, recently embarked on a book tour at the regional REI stores. He sold books directly to readers, but also his eBook and print sales reflected his activities. Other authors who either get tired, bored, frustrated or give up will see sales reflect their own attitudes about their books.
Everyone can publish via publishing services, the market is glutted, and you better know how to make your book stand out from the crowd. In the past, publishing your own book required knowledge, skills, and expertise in multiple disciplines (editing, project management, graphic design, and production). Now "publishing services" provide an amateur methodology to publish, and as a result the market is glutted with (well call a spade a spade) ... crap. Who loses in this marketplace? Consumers who often cannot discern crap from a great read. For boutiques like our company 3L Publishing this junk yard factory manufacturing makes it difficult to engender understanding that professional services that produce award winners don't cost $200.
