> In my experience, HN definitely has a problem with actively discouraging dissent
Do you think so? The "punishment" for extremely unpopular opinions seems to be a few downvotes, which are bounded below by -4. Thus the net effect is that your message appears below others. I cannot see how this can be construed as "severely discouraging dissent", it seems rather mild to me. In any case, I am not afraid to express my strong dissent on any topic here, and if anything I find the downvotes that I get rather amusing.
HN tends to keep non-Tech dissent to a minimum, or at least, if you have a differing opinion, you are held to a higher standard to defend it. I think that is a necessity for semi-anonymous online forums in this age - if you allow throwaway comments that seem anywhere from eccentric to absurd in order to troll the base, you lose the community. (reddit, 4chan, etc.)
As far as online forums go, HN seems significantly better than any other platform, considering we're also trying to self-moderate (i.e. excluding old-school forums with no voting / self-moderation features)
