Dang, I respect you and the work you do here, and I really value the HN site. I never set out to post uncivil and/or unsubstantive comments, and when I do I usually delete them or at least add an edit or reply to soften them. And if somebody calls me out on something I check myself, and apologise if I think I messed up.
I started to write a whole long thing defending my previous posts but I stopped myself. I did add up all the points from my most recent 10 comments, the total is 17. I'm having a bad run at average 1.7 points. So, yes, you're absolutely right, and I'll try to do better.
(There was one exception to my policy that happened recently, where I snarked at some person who was complaining about how hard it is for white men to speak their truth in silicon valley, from an account with a racial pejorative for username. My comment got flagged. Rightly so.)
I consider myself a hacker, I hope I'm a net benefit to the community, and I'd really like to see HN stay high quality. I did reread both the guidelines and the welcome page you linked and I am "on-board".
(I actually don't care, but your response was ridiculous and I noticed you avoided answering.)
