bit-torrent is no different than lending or giving a book you own to a friend.
Well, giving it to 9,356 of your closest friends, anyway......................
That is an absurd claim, if you will excuse me for saying so, but I want to point out something I've realized because I'm a big consumer of electronic books, streaming video, etc. --
They are changing the paradigm from books-as-objects (and video cassettes, same deal) to one consumer, one content. You can't share Amazon ebooks with friends. Everyone has to buy their own piece of content.
Huge paradigm shift getting away from Gutenberg's moveable type, and they are taking this once-in-500-year chance to up the buyer cost. No book lending. No giving away your used books.
On the other hand, a lot of classics and new amateur stuff is free or very cheap, so there is some good trade-off.
We are in such a revolution. Wow. Change is exploding all around us.
