Slideshare: Free Ebooks to Increase Ebook Sales.

Here's an interesting article from Mark Coker, the owner of Smashwords, regarding a study he did of e-book sales and the trends. Also, he wrote a book that he is giving away to help authors and publishers with e-book sales, too.
What questions does the study answer?

• Do authors who change prices frequently sell more books?
• If ebooks are immortal, how do sales develop over time?
• How do individual titles develop at a retailer?
• What's the ideal word count for ebooks?
• What word count do romance readers prefer?
• What word count do erotica readers prefer?
• What impact does price have on unit sales?
• How are Smashwords authors pricing their books?
• What are the most common price points?
• What price range earns the author the most money?
• What does the indie ebook sales distribution curve look like?
• What's the optimal price per word?
