I like the "vote up smart comments regardless of agreement" approach. My Kantian nature then expects to see interesting comments at the top. I also like the "vote to agree or disagree with the 'poll' (aka comment)". This prevents dozens of "I agree/I disagree" responses. The second approach is my first instinct.
