The problem with ebook filesharing is simply one of scale. But I think the "piracy" problem is massively over-rated.
Charles StrossBack before the internet we had a name for people who bought a single copy of our books and lent them to all their friends without charging: we called them "librarians".
Charles StrossWhat I really think is that our current model of copyright is fundamentally broken. We badly need to replace it with a different system for remunerating creators, which gets it the hell out of the face of the public (who were never aware of it to begin with in the pre-internet dead tree era). Unfortunately, the current copyright model is enshrined in international trade treaty law, making it almost impossible to work around.
Charles StrossI don't keep anything on paper (except within an actual novel in progress, at which point I need a file to keep track of plot threads, characters, and so on).
