Isn't it incredible how one can freely share one's books and magazines (I'm talking 'real' paper versions here) without reprisal, yet when one decides to share one's books or magazines in electronic form it is considered piracy. This is utter rubbish and a complete double standard.
Good literature should be shared. This is how culture grows and changes. People learn stuff. The world becomes a richer place.
I advocate the free non-profit sharing of our literature and I recommend you check out TUEBL - The Ultimate EBook Library. This is one such site that sees things the way I do.
