This is one of the rare cases where reddit does worse than digg. Digg's frontpage ranking algorithm (newest-first rather than bubble-up) means they have to have a way to bury stories. Reddit doesn't. But that means it's vulnerable to a group of a few hundred ultra-dedicated zealots.

I have some ideas about how to fix this (without digg censorship). The news sites we have now are still only version 1s.
