A configurable/optional karma filter which defaults to enabled could be the solution since there are genuine concerns for and against this feature.
Unregistered users may have karma filter enabled by default so that hackernews doesn't give a bad impression to the general public due to low quality comments; and registered users can switch it on/off at their preferences panel, then it could be interesting to analize the stats and see how many and who use it.
