Fair enough, and I agree with that.

but look at the behavior of the community right now. The highest voted comment on this post is basically a "screw you dude" and all of my responses are downvoted without any reasons given.

Below in comments I stated what I personally would like to see change, but that too is downvoted without explanation.

These reactions are reinforcing my original point: Though many precautions were taken, Hacker News is no more immune to large group behavior than were Digg and Reddit. The community has reached a tipping point.
