It'd be great if it were implemented as a peer-to-peer protocol as it'd make taking the service down much more difficult.
EDIT:
Although making the service completely peer-to-peer might be impossible, it is possible to distribute articles in a peer-to-peer way. I'm considering an architecture which consists of a peer-to-peer network to share articles, and servers to download articles and put them on the network. In this architecture, even if all the servers got taken down at least the articles which have been shared would be accessible provided that the peer-to-peer network is alive.
