Another option is to have some social cost to making comments. The easiest way to do this is to force real names - look at e.g. Techcrunch (but there are other examples) to see the impact on comment quality.

I can't see it working here, for a number of reasons, but it's an interesting thought experiment.

How would you know that someone's used their real name?

That might work when there are a small number of participants and everyone has met everyone else face to face or when there's at least someone to vouch for the identity of every participant, but it doesn't scale very well to a community the size of HN.
