I mention the The Future of the Book blog often but for good reason. Read this tidbit:
we need to convene and decide how deeply we want to connect culture and property. And when we’ve settled on a particular mix, we might think about whether it maximizes our freedom to speak, to learn and to inquire — in short, whether it leads to the kind of a world we’d want to live in. This will not be an easy conversation — it’s hardly even begun. But one way we can move towards more open cultural distribution and exchange is to make our own works as accessible as possible. We can do this by limiting restrictions on reuse to the absolute minimum, by using permissive licenses, like the Creative Commons licenses, that say “use me this way, it’s OK,” and by using copyright homeopathically rather than as a weapon of shock and awe
Then go to if:book and read the rest of the Rick Prelinger's argument.
