Turns out I didn’t understand how to read the Smashwords dashboard. The 144 free downloads for Last Night were downloads directly from Smashwords, but a chart on a separate page shows another 193 downloads through the Smashwords premium program. For some reason they were all downloads from the Sony ebook store, and they were remarkably steady over the few months the story was available there, from Sept. through Dec.
So, to update my figures in the previous post, there were 337 free downloads of the story, and with the five paid sales, a total of 342 potential readers. Still no cash for me, but I’m glad the Kindleboards authors helped me understand how to read the SW dashboard!
