HN has its share of jerks, I've had someone threaten to come by my house and beat me up (I'm pretty easy to locate) but I figured it's all bluff and easier said than done, and in the camarades.com/ww.com days I got far worse thrown at me so I've learned to live with it. But it shouldn't come to that.
The internet used to be a nice place. There were flamewars and the occasional crappy argument but nobody threatened people with bodily harm. Then the village became a town, and then the town became a big city. And then all the bad stuff that happens in big cities came right along with it, including the jerks, the swatters and the drive by shooters.
There is a Dire Straits song in there somewhere.
Sites like canonrumors.com should be neutral territory, like churches used to be, places where people can read and exchange information without harassing the owners and the moderators. If you have showdead on you can see what a 'nice' place HN is every now and then. As it gets more mainstream here too the interaction will get more coarse.
I've already made up my mind to walk when dang does.
