1. How qualified were the ebook users for the subject matter or was it like an appetizer at a party too good to pass up?
2. Last time I checked, Kindle still does not allow for pass along of an ebook, which means that the SINGLE MOST POWERFUL marketing technique, word of mouse(he he) is NOT an option with their model. Shame really.
Ok a solution?
I recommend and use widely, the Feedbooks services(see this link for a sampler) or this one too which provides these features:
A. Download in Epub(most readers); Kindle(amazon) and PDF(computers using Adobe editions). See this link for the Missing 100 Millon Ebook potential readers.
B. PDF at least allows for pass along among communities and around 95% of computers use Adobe.
C. No time limits and some helpful analytics on usage.
Might want to consider these options when deciding on which Free Ebook strategy to adopt.
