I saw this item via author Anne R. Allen. Smashwords, which about a year and a half ago was drawing eye-rolls from indie authors in the know, has just been named #69 on Forbes list of America's Most Promising Companies. I don't see them defeating Amazon for publishing dominance anytime soon, but I do see them as a great place to put my book and to distribute to other channels.
As of my second release The Family You Choose, I am making my books free for the first week of their lives through Smashwords. Want to get my books for free? Please sign up for my newsletter (link on the right) and I'll include the coupon codes when I announce my new release. (And yes, Kindle owners can use it too- one of Smashwords' formats is .mobi.)
