I'd try to severely decrease total # of comments.

Really bad comments are not the root of the problem. Simply having large number of mediocre comments crowds out and discourages thoughtful discussion from starting at all.

I'd say:

* create some real cost to making comments

* make bad comments disappear/not display at all with time

* make things less democratic -- to encourage good behavior identify users who have this behavior and make this behavior more prominent programmaticly

Making it cost karma to comment would be one way to do that. I could also do something like slashdot and reddit do, and not show comments below some threshold.

But that doesn't solve the problem of bad comments that get tons of upvotes, in fact it will probably aggravate that problem.
