Being a regular HN reader, I often see people criticizing the quality of comments on HN.
While I too have experienced such negative feedback few times, I still knew there were plenty of positive-minded people here who are ready to help others.
So when I read the replies to this thread : http://news.ycombinator.com/item?id=5198352 ,
I was glad to see so many HN users coming up with really helpful tips and positive responses.
I think anyone who criticizes HN everytime they get a negative feedback should check the replies in that thread.
