This is one of the things that Slashdot did right, and something I don't believe any other community like Reddit has tried at scale. My crazy dream: Something like HN or Reddit, where hovering over the vote arrow brings up a small list of reasons. ^ (Agree/Correct/Insightful/Funny) v (Disagree/Incorrect/False/Flamebait) All votes are counted as normal and the algorithm everyone sees is otherwise unaffected, but the magic happens where you give users the ability to sort by score and reason, rather than just score. This cancels out some of the hivemind suppression of unpopular or minority viewpoints, since most people are going to just click the bare button (which registers an agree/disagree vote). With one click, you can see insightful-rated posts which might be otherwise buried at the bottom of a thread. Similarly, moderators can sort by flamebait and perhaps take action.
