Color me skeptical about stopping drift, though. It'll be neat to be proven wrong. I wonder how you'd prevent the system from just emulating the editors, instead of the audience. Now with YC perhaps that's exactly how you'd like it, but for a more general purpose site I'd want more of a user-focus than an external-editor-focus.
For the newer people, thank you for the link about what the appropriate topics are. I think a time or two I asked "what does this have to do with hacking?" Now that I know the larger focus, I'll be more reticent.
