In theory, news would be more rebust than mail, because of its distributed nature and it should be possible to make news work without relying on the DNS.
USENET/news has a few properties which make it reliable. The most important is the flooding method of propagation. Second, it propogates over multiple types of transport (UUCP, TCP/IP, Satellite, Magtape via Fedex, etc). That combination results in an extremely robust mass-distribution method for messages. It is also extremely fast (a few seconds for the "core" news sites), but has a very long tail. Mailing lists, web sites, etc. have a bottleneck in the distribution process. But are much better for controlled, or authenticated information. The CDC may get hacked, or may be wrong about Anthrax, but if you go to the CDC web site it is highly probable the information on the web site is from the CDC. The lack of control of USENET is its strength and its weakness. It would be interesting to come up with a protocol that combined the robust flooding algorithm of USENET with a way to verify the source (i.e. prevent spam).
