You can make money by simply uploading old books on Amazon
For books past the copyright, people can upload the books and format it...add some links, etc...and charge $1. And make oodles of money! Seems like a great business plan. I for one, do not have time to figure out how to upload and correctly format one of those books. In any case, the time it would take to do it would be worth more to me than $1.
So MobileRead should think about about uploading all of its books onto Amazon.
