What some folk are thinking that paper books will go the way of the Audio CD business. So far I just see a change in medium.
Since you don't have to get a publisher to agree to print your book, you'll see more choices in ebooks and we'll still have paper for some time to come.
Are ebooks replacing paper books?? I'm worried that in the future, printing companies will go out of business and our world will turn into full-ebook-technology...
