Here is an excellent article that supports my opinion: The Stigma of POD by Aaron Shepard. I fully agree with his conclusion that the primary market for self publishers today is not bookstores at all. It’s online booksellers, Amazon in particular. And POD is by far the most efficient and profitable means to sell to that market.
Case in point is the incredible success story of Amanda Hocking. Penniless and frustrated, having spent years fruitlessly trying to interest traditional publishers in her work, Amanda needed to raise Some money to make a trip to Chicago, to see an exhibition about Jim Henson, the creator of the Muppets. In desperation, She made her unpublished novel available on the Kindle, and has since sold over 1.5m books.
So I ask you: is this not the most amazing moment in Literary history?
