There are people already sharing eBooks out there, .. and they do it simply because they love books. You don't buy a second copy of a book, cut the spine off, lay each page on a scanner, run that .tif through an OCR (Optical Character Reader), hand edit the resulting output for errors and then post it online if you don't love the book. it can up to 80 hours to turn a printed novel into an eBook. I figure if someone out there is willing to put in 80 hours of work promoting my book, then I'd prefer they do it in a way that gives a better return to me.
