You really don't think pg's comment was meant to hurt feelings?

This is pretty freaking harsh, and I imagine would trigger a feeling of defensiveness in almost anyone: "Maybe you think you're making some sort of important point here. Or maybe you realize your comment is inane and you think it's witty. But (perhaps without realizing it) you and the people upvoting you represent one of the worst forces at work in the world."

It's incongruous with the site guidelines, in fact: "... Be civil. Don't say things you wouldn't say in a face to face conversation. When disagreeing, please reply to the argument instead of calling names ..."

I do not think it was intended to be personal, but somehow I find it strange that "feedback" gets bashing. Isn't that what "Show HN" posts are for ? What, you care enough to post your question/impression/opinion about an upcoming app, and you are treated as a member of "worst forces at work in the world", a servant of the Devil or something.

In my book ANY feedback is valuable, even the ones who say your app is crap/irrelevant/missing a key feature. If one if scared of getting feedback, then entrepreneurship is probably not the right occupation for them.

There is no name calling there. He's covering the bases of the commenter's mental state, then explaining the unfortunate circumstance he sees. The "maybe you" phrases could be interpreted as harshness, but I think it's more likely that they're to be taken exactly at face value, and that pg wants to call attention to this circumstance.

I honestly don't believe it's fair to not interpret the maybes as name calling. Even so, the "But you ... represent one of the worst forces at work in the world" cannot possibly be defended as not a personal attack. Come on! I would not say that to someone's face, and it certainly isn't being civil.

Then you admit that the content is okay, but that the wording of the last bit is unfortunate. Looks like an understandable mistake of editing and point of view, not a deliberate attack.
