I think what kyro is trying to say is, if you don't like what you see on HN - why not submit the type of articles you'd like to see, hopefully starting a trend?

imho it doesn't help that your post sounds more like whiny bitching than constructive criticism

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.

You essentially just called a community stupid. When provoked with such nonconstructive criticism, I'm not sure why you would expect said community to respond with anything but "No, you're stupid."

and are you helping the site out by flagging down the articles you have problems with?
