I read Paul Graham's "How To Disagree" (http://www.paulgraham.com/disagree.html) and a blog "One a Day" (http://avc.blogs.com/a_vc/2008/03/one-a-day.html).
Would creating a scarcity of number of comments that can be posted a day (say 3 comments a day) make people think twice before commenting and probably reduce DH0 - DH3 type of responses?
