I don't think all negative comments are looked down upon. At least for me, I don't feel uncomfortable criticizing something on Facebook if I feel like I have solid reasoning to justify it. To me, adding the Facebook commenting system to Techcrunch seems to be transplanting a lot of what makes HN work as a place for discussion: - a persistent online identity that you care about - having to sound reasonably intelligent or to contribute meaningfully, in order to get votes / likes. - comments are ranked, so the comments deemed the most valuable are the most visible.
