This was my first day. I stuck around for a day or two, then I just logged out and stopped participating. Just use this as a site to find links, and when you're not logged in there's no incentive to go see what people said in reply to you, and no focus on karma score or anything. I don't know if the site requires a certain level of karma to submit new items, but I don't really feel like submitting things here when I don't feel like they'll get a fair shake. (There were good discussions on some of my other comments, but another one where it became clear that I no real discussion was possible because of ideology combined with the "fucking idiot" comment were enough to have me stop participating.
This is just FYI. I'd love for there to be a place to have good discussions with people. I don't know how to make HN that place, and so I'm just going to use it as a source of articles to read.
I think all news sites that allow downvoting end up operating as a sort of "smear the queer" system for punishing people who have a minority viewpoint, without regard to how well they articulate it or even what they are actually saying (in some cases.)
Edit: Yes this topic got me to log in, and I'll be logging out now. I don't really want to debate the topic that I got attacked over, as my original comment was actually trying to defend someone else's perspective. Please whether you agree with me or not, take this as "market feedback" of what a new user experienced, and why I'm not participating. Maybe I have thin skin in your opinion, that's fine. Maybe I'm way too wordy to participate on a site like this! That's fine too.
