I second that! HN has become a bit of a echo chamber; more or less as a direct result of the decision to have down-vote privileges scale with the number of HN commenters, thus disproportionally weighting down-votes in the direction of those who have been properly cloned. Although, I must say, the echo chamber effect is not as bad here as it is on (for example) the Derek Sivers blog [[ http://sivers.org/blog ]].
