I just learned from stalking Mark Coker on Twitter:
Pulitzer Prize-winning reporter publishes on Smashwords – http://bit.ly/7eAPYq “Newhouse said he also has a new electronic publication being offered for sale online by Smashwords! It’s a diary of Newhouse’s experiences in the two years after he won the Pulitzer Prize.” -Richard Ecke
Newhouse’s book: http://www.smashwords.com/b/5683
So, it looks like Play Fling will be in impressive company. Legitimacy indeed. Go, Smashwords, go.
