I haven't been around HN long enough to really notice a shift in the negativity of comments, but I have been around long to realize I could very easily become part of the probably that a lot of you talk about: signal to noise.<p>I keep coming back to HN because of the caliber of minds that offer up advice, criticism or personal thoughts on a daily basis for little in return. I envy the amount of collective intellect that HN users have, and yet therein lies the problem - I envy it, so I want to be part of it.<p>I'm considered the most intelligent person in my family and in my previous job I was the "goto" guy for the tougher questions, the hard assignments or just general advice on your random everyday things. I'm sure a lot of you are familiar with this sense of worth. You're admired, needed even, and feel like you have something to offer.<p>On HN, however, I often feel like I have something to SAY, not necessarily something to contribute. This realization has made me very cautious about posting unless I really feel like I can add value to the conversation. Commenting, as I understand it, should really be about just that - adding value.<p>Having said that however, I also think there is room to embrace newer users who don't really understand this mechanic. Down voting a comment to oblivion doesn't help with educating those who really don't understand why they're being down voted, whether or not it's a troll or just a misguided newbie. Repeat offenders are a different matter and I can't really offer up suggestions on how to handle them, but for the newer members of HN who just happen to confuse something to add with something to say - hopefully giving them a casual nudge in the right direction will really with keeping HN on track.
