The idea of decentralizing websites has always seemed great to me. Specially when big-name sites are taken down like TPB and KAT and "clones" are released and you're never sure of the authenticity of the clones and who is running and profiting from them.
I know torrent sites may seem shortsighted, but thats just an example of websites in constant threat of being shut down. Journalism sites such was WikiLeaks can benefit huge from decentralization as well.
