I never used fark. Did they make a change to the structure of how users interacted with the site, or did they make a change to the UI only? digg v4 was a disaster, but the exodus started before that when digg removed threaded comments. Related: Wikipedia changed what pages actually looked like by moving a contents navigation bar to the left side and minimizing some other features. It's the last UI change in a major website I can think of that didn't make me grimace.
