Short stories for print might not be such a good idea, unless it's a collection. Separate short stories on Kindle or Smashwords as ebooks can work well. I have two erotica short stories that are averaging around 10-15 copies a month each as ebooks. (One of them sold 45 copies on its first day of release.) Last week, one of of them was number 4 in the top 100 gay and fiction short stories on amazon uk I didn't know how to make a screenshot at the time, so I couldn't save it, which was a pity.

So I think ebook short stories can do well

Take care,
