This attitude is the reason I don't blog anymore. You don't just disagree with them. You're put out that they're writing at all. I understand where you're coming from and I sympathize but that attitude is oppressive and stifling and I wish people would dial it down. I'm one of the culprits too (hoist me up by anything I've written about pg). I hope people call me on it too.
For me, it's absolutely not hacker news. I don't know what it is.
If they want some respect, write some software! Blog about some cool technology. Solve a hard problem.
edit: deleted my previous posts. I'm not going to comment on any more of these posts.
