I do not read the comments on HN of the pieces I write. I used to. I used to love hearing really smart people help out with whatever was puzzling me. Perhaps I can get back to that. But damn, this is a negative bunch. Whatever topic, whatever opinion you have, it's somebody's hot-button issue and somebody else doesn't understand what the fuck you are saying. Sometimes this is the same person. Most times this is dozen…
If I may offer a counter point. One of the complaints about users on HN is how they treat Show HNs. The worst thing is arguably working on something and getting totally ignored. The second worst thing is probably getting verbal abuse for your project, from people you respect, no less.
When this happened to me (being ignored that is), I decided to try another community for feedback. It was 4chan/g. Now 4chan has the reputation of being somewhat of a sewer, but my experience was as different as night and day. People were interested, and above all: friendly and constructive.
So why am I not hanging out in /g then? I believe that HN has a higher ratio of users who are "my kind of people", commenters who I feel I have a connection with. But as it is, this comes at a price, because HN can be a less civil place. I don't this is written in stone, however, we can and should work on improving this dynamic.
