1. If a bad TechCrunch article makes it to the top, is it because the karma system of HN needs refinement to mitigate perverse incentives? 2. Instead of a ban, would it be better if HN users slightly change the way they read articles or can HN show top X comments with each article title? E.g. for 1., even though if a user writes a negative comment about an article, he/she may be inclined to upvote the article so that his/her comment is read resulting in an unsavory article gaining much attention. E.g. for 2., a HN reader sensing a tabloid article from the header can go to the comments page first. Or better still, if HN can be tuned to just show top X comments, then would it solve the issue?
