Tell HN: Uptick in mean-spirited comments

I've been visiting Hacker News for just under two years, and recently I've noticed a significant uptick in mean-spirited comments. This echos a recent comment by PG, "There are more dumb and/or mean comments than there used to be..."

As you are commenting, or up-voting and down-voting comments, please be conscious of how comments might affect others. This is a fantastic community of incredibly bright people. We should be able to engage in thoughtful debate and discussion, while remaining friendly and polite.

Thank you everyone!
