At the time I'm reading it, your second comment (http://news.ycombinator.com/item?id=1799442) is neutral at 1 point. That is not a symptom of people acting "toxic" and trying to "discourage" you. It was a good question, but nobody seemed to know much about it, so it just sort of sat there.
Your first comment (http://news.ycombinator.com/item?id=1787833) is at -3 points. Unfortunately, as it's five days old, I can no longer put it at -4. You stepped into an admittedly poor discussion about specific reasons why SO might need less servers than Digg, and posted a flamebaity generalization with absolutely no support; you didn't suggest a reason that .NET might be faster than LAMP, nor any evidence that it might be faster, or what it might be faster at. You just dropped a one-line load of an opinion and left. I absolutely am on board with being maximally toxic and discouraging toward the comment you made there.
