Well... I'd say it isn't solved. What.CD went down. Fuck, that still hurts.

People now speak of Google Books as a library of Alexandria, but What.CD was the real thing. Google Books was barely available to anyone, ever.

That shouldn't be possible the next time. How though? Distributed metadata curation is a problem we haven't worked out well. I know I haven't.

Especially if the metadata is stored on and for data stored on a diverse set of platforms, like "not only BT", but also Freenet, HTTP, FTP, IPFS... It just doesn't exist.
