To me, your point was completely lost by the fact that you choose to attack people yourself, rather than highlight the stories with positive comments. You didn't really do a meaningful comparison, but rather just looked at two stories' comments and decided to write a rant about it. What would be cooler would be to take an Opinion Analyzer and run it over the comments from all stories for a week, and get a true idea of the factual amount of positive/negative.
As I said a bit ago on another story, sometimes shit sucks. We can't always be positive when there's so much stupidity in our field, and trying to paper over it with positive thinking isn't necessarily constructive; sometimes it's actually damaging to progress. When somebody says that something fuckin' sucks, they're probably full of bullshit, but maybe they're onto something.
