The only thing that really worries me is that some of the content-free negative remarks about Gruber/Apple/Groupon/et actually seem to get upvoted rather than buried these days.

I always felt HN as a community was a little too strict by even downvoting some genuinely funny remarks, but it seemed to work in keeping a high quality of discourse. It baffles me how the same community can nowadays upvote ad hominem attacks. Something about HN's ability to police itselfs seems a bit broken lately.
