I started a long time ago. Still don't have many awesome stuff that was on what.cd. And there's much more I don't even know about yet, which probably also was on what.cd already. To continue using our metaphor, a vast personal book collection is still less than a real public library. It's still a lot about sharing. I'm proud of my collection, but in terms of significance it's not comparable to that of entire what.cd, not to say the Library of Alexandria.

That said, we still should think about fire-resistant public libraries, not just personal collections.
