The wiki model (without tweaks) isn't appropriate for newspapers, blogs, discussion forums etc though. Maybe no system would be ideal for all of them. I think what I want is something that allows for technical improvement while maintaining authorial intent and "ownership" (in a conceptual if not legal sense) without optimising for consensus-gathering. It's also not everywhere. Maybe what I'm after is a browser extension or something...
